Hi3512 Firmware

I have sourced a hi3512 camera from a supplier in china. It apears to be a HiVision chip, it comes with a really crappy firmware. I need to get a custom firmware built and wanted to look here.

We have a small budget for the project, if anyone is interested in helping out or taking on the project it would be most helpful.

Please see attachment for camera description. I can arrange to have a camera shipped to whom ever would like to help us develop this.
