Modifications To A PHP local business directory script

Hi, I am planning on purchasing this script in the near future [login to view URL] demo : [login to view URL] When businesses sign up and list their businesss they can add their products to their page. as you can see at the bottom of this page [login to view URL] - I need the search function edited so it searches keywords for products and the descriptions, and lists them on a seperate table on the result page. - A shopping basket needs to be created so people can collect products from different businesses. however i do not require them to be able to purchase the items. this is just for show and they will only be able to print their shopping list off. - I need a new type of free user account so members of the public can add ratings and use the site. - Facebook login integration needs to be added to all user account types Lots more constant work is available for the best people at the right price, On this project and many more. Thanks in advance. Work is due to start in 2 weeks. Please give me quotes. thanks.
