Module development and code questions

What is our project?
The project that we need help with concerns the creation of a new Drupal module. This module allows for the creation of files that can be downloaded, either free of charge, with the ability to donate, or specify a price, and have the ability to charge before the download. The module would empliment several key features:

Title (of the file or document)
Topic (subject of the file or doc)
The file itself
An abstract of the file or document
An image(s) to accompany the file or document
Price for the file or document
Poll or ratings method for the file or doc
Forum for the document (For readers of the document to hold discussion)
Comments about the document (Available to the public)
Author of the document
Roll of the author (Developer - Member)

We are relatively new users of Drupal and we have already come to appreciate Drupal's excellent design and flexibility. Unfortunately we do not have enough experience programming in PHP and MySQL to develop this module (Publication Module) ourselves in a reasonable amount of time. We do have some experience in programming in C, Perl, JavaScript, and HTML etc..., so we do have a basic understanding of the concepts that will be required. We will be able to provide more specific, psudocode, layouts, and input and output vars as a result of this experience.

The developer will needs to have some experience with (the more the better):

I'm trying to write a new content module. It'll have a title, a text body, and up to 10 images. The images will run as thumbnails along the right side of the view. When uploading, it'll always have one "attach image" field, unless there are 10 attached images already. It'll use the image module to create thumbnails, and maybe one day it'll create galleries. The goal is to let people post images without requiring anyone to write any code, and without dealing with img_assist.

hi im new to drupal and i was wondering if some one could help me or show me how convert a php script (6 files) to a drupal module. im still trying to figure out how it all works :(

I just added the ability for the bookmarks module to sort bookmarks in folders. Download it from my sandbox to be a beta tester. I want to work the bugs out and get support to add the patch to the official bookmark module. Drupal 4.7 only, ATM. Submit bugs to my contact form, or if you have CVS access, just commit fixes to the copy in my sandbox.

i want to know if there is a function to determine if a particular module
is enabled or not. I'm not being lasy i have searched but to no avail.
