If you want an easy to use, cheap solution, use PIC.

If you need more performance, use an ARM such as the Philips LPC2138.

Sounds like you need a contract programmer.

You can use the free evaluation compiler from www.htsoft.com.

First, you need to program the bootloader in using a programmer such
as the ICD2. The bootloader is designed for people to upgrade their
circuits, when they don't have access to a PIC programmer.

Sounds like you need to read a book on programming, or talk to someone
who has done it before!
