megaohmeter and dielectric strengh

I need the design / schematic for a composite instrument in order to measure insulation and dielectric strengh.

megaohmeter section:

- measurement voltage: programmable, from 100V to 3000V dc

- insulation resistance range: 200Kohm to 200Gohm autorange

- 1% accuracy

dielectric strengh section:

- testing voltage: to 6000Vdc, 3% accuracy

- maximum current 5mA

- current measurement: 1% accuracy

the two sections must share the high voltage generator part

only the analog part is required (voltage and current generation, amplifiers...), i will complete the instrument with the microprocessor part, providing the necessary analog and digital I/O

Only bidder with a proved experience in analog / instruments design will be considered
The project must be delivered using some major CAD (Eagle, Orcad)
