Custom Joomla modules and components for auto parts website

Hi, We are looking for a programmer who can write (customize) several modules. We need a module similar to this website [login to view URL] -> when you choose a make and model from the dropdown menu above in the left section only the not-empty categories appear. Currently we are using "product types" of joomla to show the products for the make speciffied, so it will be better that the new module would have the same function (checking the product type of each product so there is no need to create hundreds of categories for each model). We would need also another module with the same funcitons as [login to view URL] for classifieds. There would be two sections "PARTS" and "USED CARS". We also need: - search function "Prices from...to..." - in the browse section you could choose when the classifieds are added. When you choose eg 7days please see how the number of the classifieds in each category listet below changes - from the Search modlue (on the left) there are also the samo optiion - price range and when the ads are added - if it is possible to be made we would need the website to be linked with some portals (Please view "Dealer Info" in the left section) - there are 3 types of accounts - standard (free), premium (shows the ads to the top of the category) and trade profie (a subscription) When posting your offers could you please separate in your post the prices of each component. The price may exceed the specified budjet according to the difficulty of the project. Regards.
