Customised Version Of Coppermine

Hi, I require installation (on [login to view URL] hosting) of a customised version of [login to view URL]: * Tag each uploaded image with multiple keywords all selected from about 6 different dropdowns (as well as a few free text keywords). * Search form includes free text keyword fields and selecting of keywords from the same 6 dropdowns. * On the image page download links to download the standard size and origional full size image. * Setup of category structure (should be standard) I need this in less than a week from today. Please advise of costing and timeframe. Thanks
