Affiliate search engine / Price comparison type website

Hello, Thanks for looking at my project, I am looking for costs to have a script/search engine created that will allow users of my website to search for prices for car hire on specific dates in any location my affiliates offer and across various different car and van types. There will need to be a filter system (so for example - vehicles with and without air conditioning or automatic and manual transmissions). The best example of an engine that I have seen so far is found at [login to view URL] and to be honest that is pretty much exactly what I am looking for. I look forward to hearing from you and if you have any questions, just ask. Just to clarify, I am NOT looking for you to make an entire website, I can do that myself. I am only looking to have an affiliate search engine created which I can then integrate in to my existing website(s) and any I should build in the future. Thanks!
