Does anyone know how much it costs to obtain a temporary work visa for South Africa?

Hi, I went through this process for myself and my family 2 years ago, my company paid. We used an agency to obtain the visa but we had to supply all the documents. We had to get Chest X rays, full medicals, Police Clearance reports for every place you've lived in the last 10 years, certified copies of all education certificates, certified Copy of your SA contract.
Estimate 1000 pound for all these docs plus the agency fee. Process took 4 months. My work visa was valid for 2 years, I have just started getting a new 2 yrs work visa, this is basicly the same process/costs.

Also the jabs for wife and 2 kids was approx 1000 pounds.

a 40ft container packed, shipped, unpacked with all our belongings was 10,000 pounds.
