Fixing a website recorder device

I'm creating a website devoted to the collection of regional accents of languages. In this website there is a text for the people to read and a recorder which activates the PC integrated microphone. The recording application uses Flash. In a preceding project a freelancer developped for me the recording device for the website. I asked him to make the recorder save the wav files into two PHP web hosting sites. As a matter of fact he actually programmed to save the wav files just into one of the websites and since I haven't worked onto the website for a while, that only account expired. So I need someone to fix this very problem. What I need is someone who: can access the software that the former freelancer did & can modify it; can find me some serious PHP web hosting sites*; can modify the software to save the wav files into those websites; can complete that whole work. *The PHP hosting sites must be capable to receive quite huge files. The wav files might be recording up to 20 min long and they have to be .wav for I need a certain quality (at least theoretically) of the sound. Moreover it's better if the hosting sites offer me accounts which don't expire. I'm offering 40 € for this actually quite small project.
