****Much Needed Drupal expert advice!!!! Can I use Drupal for my site?

So I received a grant to establish a social networking website for artists in the Southwestern PA area. I made the mistake of choosing a programmer that gave me a good deal, but I think he is horrible. I was quoted anywhere from $100,000 to $50,000 to $8,000 to create this site. We are supposed to launch on April 21 and most of the fuctionality still is not finished and it is messy and sloppy and runs really slow. The programmer is using cold fusion.

What I am wondering is if Drupal would be able to handle a site like this.:

Here is what the programmer has done so far:

I think it looks cheap and like he doesn't know what he is doing.
Also There is a back office component.

password:password

Firstly: Is it possible to create a site like this in Drupal?
- Is it hard to do, even if I am new to php and mysql but have some web design experience?
- After this verision of the site launches, how hard will it be to transfer all the data that the users have uploaded into their profiles without loosing it and without them having to change their passwords etc...?
- Is there anythig else I should consider?

Here is an summary of the project I want to be on the site:

Summary
Articulate; Pittsburgh Creative Network has applied for non-profit 501(c)(3) status. Our mission is to create a "virtual community" that will provide artists with the resources that they need to be successful in their careers and to strengthen the visual arts audience in the Southwestern Pennsylvania region. Articulate will serve as the premier online resource and centralized hub for artists, galleries, arts organizations, and the general public (both art enthusiasts and passive viewers) for the Southwestern Pennsylvania area. The Articulate website is an E-Networking, E-Commerce website. In addition, Articulate will energize the local art community through non-virtual exhibitions, educational programs, as well as "Go Public" - art in public spaces. Articulate is technology driven and will bridge the gap between artists, galleries, art organizations, and the public.

"We need to let go of our favorite habits, old models, and best practices to make room for New Things- new models, new knowledge and new possibilities." - John Waters, Creative Director of Waters International, Inc.

Articulate is creating something new! - A virtual community to broaden the available possibilities for information and idea exchange between artists, galleries, art organizations and the public (i.e. the Art Community). We believe that through the web with its two-way, multiple channel, "many to many" connections, Articulate will enrich the Art Community's communication palette and ultimately create a voice for the art community as a whole. Articulate intends to capitalize on the unique capabilities of the web: the ability to connect with people, receive feedback, customize information to meet specific needs, provide for easy and immediate transactions (E-Commerce), collect analyze and store date, and collaborate on new ideas. The Art Community may join Articulate's virtual community by becoming a member. Members may communicate through comments, blogs, messaging, reviews, and essays. They may upload their artwork and post it for viewing and for sale. They may also post information about themselves, such as an artist statement or biography. Non-Members may navigate through the virtual community and view member-posted information, and the members personal profiles. The Non- Member may view and purchase displayed artwork directly from the virtual community as well as rate the artwork and galleries.

The ARTICULATE web application is an e-networking, e-commerce site.

No names will be on the images (for non-discriminatory selection, until a specific piece is selected). Articulate’s advisory board then votes on the pieces that were submitted. The advisory board may also post comments along with their votes. All members of Articulate may apply for these opportunities – The pro-Artist may apply for free, all other members may apply for an addition application fee. When voting is finished a final e-mail is sent to the executive director, who then sends out personal acceptance letters to the selected artists.
