Please help

I have a prototype build (.NET) for a new application that will overcome issues millions of people have.

One problem: I am not technical and need some assistance

Question 1 - The application must be integrated with the entry level phones (It can be developed in Java based phones but that is not the primary target market). Is it possible to access and do development on the platforms these entry level phones uses?

2. Is it possible to build logic around the "sound card" function of the phone - sound activation etc.?

3. Are there developers out there that can do this, or do I need to contact Nokia product developers (Which I don't want to do as a start.

Thanks in advance
