Classified Script Small Modification

Hi All, I already have a classified script (osclass) and would like to get some very quick modification for the same. Here are the changes that I am looking for: 1. Remove location field from the submit form. 2. Add URL field in the submit form, the field should be displayed as the download button in the listing page and not the URL. 3. When someone click the download button, it should take the user to the third party site (download site) and a bar with the logo should be displayed on the top of the third party, so that user can go back to the classified website easily. 4. Auto suggest feature for search box. Note: The classified website that I want to use is [login to view URL] and the theme that I am using is [login to view URL] Note: The budget is small for this work but I would like to work with the selected bidder for more complex work in the near future. Thanks Shubham
