Paleochannel identification -- 2

I am looking for experienced help in identifying subsurface paleochannels in an area in South-Africa to be used by a small alluvial diamond miner. I am looking for someone who has extensive experience in paleochannel identification and mapping and knowledge of geophysical surveys and understanding of subsurface paleochannels. When applying please clearly state what method you'll use to identify the channels and also include samples of previous work done.

Project needs to be delivered in a mapping format to be used in global mapper.

Successful completion of this project could lead to more opportunities in similar areas.
