Download files from sites like wupload, filesonic, hulkshare

We need to have a webservice built which will be passed a download link for a file stored in a locker such as [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] We will have premium accounts on some of the lockers but others we will need to download using the free options. To allow the webservice to have new lockers easily added the webservice class will need to be structured in a modular way. The service will need to be written in PHP and will also connect to a database to get a list of proxies that are to be used randomly when downloading. All downloads will be stored in a local folder. The nature of this project means that the work is likely to be ongoing with small modifications to the specific classes for each locker being made periodically. We are therefore looking fro someone with high end php skills able to think around problems and deliver stable code efficiently. We also have additional functionality we would like to add to this however this is the first step.
