I have not flown a Q-200, but I have 20 hours in a Q-2, solo and with passengers, from sod and paved runways. I would think it would function fine from 2,000 ft (clear approaches and departures) with no serious cross winds.
If the owner/seller would demonstrate simulated 2,000 ft operations and take you along it should lessen your concern. If it is a matter of you not being comfortable with higher performance on that runway, look for something a little slower. If you are a smooth pilot and cautiously self confident it helps. You have to make the final choice, as you would on each flight. Q-2's and Q200's are great airplanes.
