Martin County Valuation for inheritance

I would like information on who to contact for an appraisal in Martin County? I am in need of a basis value for my holdings in Martin County, sec. 9, Blk. 35, T1N, T&P RR Co survey, A-45, N/2 and SW/4, from inheritance in 2011. Would like a value with production and non-producing. I just sold some interest but retained current well production so what I sold is non-producing. Any help with this would be greatly appreciated.
