Grund Source Heat pumps - South Africa

Hello All - I have searched the forums and unfortunatley have had no luck! Hoping this community will be able to point me in the right direction:)

I am looking to install a GSHP on my property - I have just bought and will be redoing the whole house etc and am really into being self sufficient as possible.
I am resourceful and stubborn (am a qualified Civil Engineer - however have been in the IT field for the last 15 years)
I plan to do a lot as DIY projects (Solar heating for Hot water, solar electricity etc) but realise GSHP are out of my field and was wondering where do I get them in South Africa?

All the people I have talked to do ASHP and not GSHP - can anyone tell me if they have done a GSHP project in SA, who to talk to, what do they cost etc, or do I have to impport one??

Cheers
