Wordpress Plugin Modification

Hi, I have a wordpress plugin of which I am the original author. Basically, it reads an RSS/xml feed and creates posts from the feed and also reads testimonials and adds them to the created articles as comments. I need this addon modified to work with an XML feed from a specific site of mine. I would also like to add a few new features as well. SInce I am focused on the new site and getting it online I do not have the time to modify the plugin with these new features. Here is a list of changes that I need made: 1. Change from my current logo to the new site logo. 2. Remove the ability to pull feeds from anywhere and pull only from the new site (remove URL field) 3. Add the ability to select keywords and/or category from main site by pulling category list in either json or xml from main site. 4. Convert the inserting of testimonials to inserting of user comments and ratings that are included in the xml feed 5. Include image provided in the XML feed 6. Add the ability to pre-pend or append any post with small ad from our site 7. Add a widget feature that would rotate products from the new site like ads on the sidebar. The site can provide the ads via json or xml based on criteria. So only the display part needs to be added. I need this project completed within a week. Bids without PM are not accepted . Please bid only if you can complete this project. I can send you via PM a link to where you can download the current plugin from my site (it is a free plugin) if you want to look at it before bidding.
