How much should a plan for six bay garage cost?

[Marian Smith]

My auto mechanic got a 50k price/estimate to get the site report and design for a 6 bay auto repair shop that he needs in order to get a price on building the property. It does include a retention pond...which I wonder if his realtor should have found out about beforehand. There is a cement drainage culvert but the city evidently says it isn't enough. He is very discouraged. Is that price for real?Does anyone use someone a tad outside the Round Rock,Texas area that may be more reasonably priced? but dxperienced enough that the bank will be okay with him? Thanks.$7
