Drupal 7/Commerce Kickstart help wanted to set up store and import data

Hi,
new to Drupal 7 commerce and feeling a little overwhelmed. I have a brand new install of Drupal 7 with Kickstart on it and I would like someone to help me tweak my Commerce site with the config I need for the store. Basically I want pricing to be different depending on the user that logs in (e.g. trade prices versus regular joe), I want to set up my taxes and I want to import my data which has thousands of items in Excel with all their criterias (size, manufacturer etc... ). That's it. :) Contact me with hourly rate or ballpark quote and some reference websites.
This is rush!
Thanks!
