domain Bulk name appraisals worth their salt?

[Z44]

Does anyone know of any legitimate appraisers who charge reasonable rates for appraisals and utilize more comprehensive and extensive analysis than, let's say for example, LeapFish or Estibot? I'm looking for such an appraiser (with references he/she might not mind sharing) who can appraise about 400 domain names using techniques utilized by the more in-depth analyzers for a very reasonable rate. I will need he/she to disclose the methodology of the process including the venues of analysis and to be prepared to stand by it with hard-data proof. Any clues? Thanks. Please no Estibot or LeapFish gurus - I can do that myself, and ultimately of course, it is impossible to accurately appraise any domain name as market drives the number. Thanks!
