Magento Extension Customization and Social Login implementation for existing magento site.

I have an existing Magento eCommerce Website link: www.artcanvas.in. I need the following to be done: 1. I need the extension called Customer Product ([login to view URL]) to be customized according to my needs. 2. There is already an extension for social login in the site but its not showing in the ajax popup login when the page is opened. So social login needs to be added to the pop-up login page as well. Customization of the extension are as follows: a. The create product request button needs to be removed from all product pages. b. In the product requests page where all the requested products of a user is shown it should show : Product name, date, status, sales statics, request details and at the end it should show total amount sold from all products for a user. c. In the product request form page its should have input area for: product name, price, brief, quantity and image upload. Any other details i will give when needed.
