Modify an API form

Hi, I need someone to help me complete an API form. The current api form is pulling data from CampusBooks. Currently, the script is looping (looking up books and prices)- which really slows down the search. I need the script to do the following: The keyword, author and title should be a text call to give results. Then the user should pick a book and request prices (see [login to view URL] as an example of the user flow). Once the form is doing what it needs to do, I need it placed on a wordpress page. I need this done as soon as possible.
