I suggest you monitor or ask questions on:
The short answer is that you need to have a SBC (single board computer) with flash. Then you need to program it. There might, or might not, be cheap SBC's with the motor drivers installed. If not you need to select a motor driver. I would suggest A3977 from Alegro, it seems to do a lot for you at a cheap price.

Here are some Allegro links of interest:
This has instructions for a cheap kit.

Be aware you that you have some learning to do; but nothing that is not freely available. If you can't find a board that fits your needs use one of the cheap board places and thier software to make your own for well under $100.
I strongly suggest you make up the PCB's from manufactures recomendations. It sounds like you don't have equipment to troubleshoot problems.

I might also suggest:
Motors & Drives
Dave Polka

For your last question about memory. Make sure the microprocessor you use has "flash" so it can remember programs and scripts/instructions.
