Cost/Recommendations for inspections - Commercial in Houston, TX

[Daniel Lioz]

I am looking for recommendations/cost for an inspection for a small warehouse type of commercial property in norther Houston, TX. 

The property is sitting with water well and septic tank which I need inspected as well as the HVAC and roof/structure.  What are some costs or recommendations can anyone suggest?  Thank you.  I wanted to get an idea on the costs before I move forward with a potential investment into the property.  Never had experience with septic/well in commercial properties before.  Any words of wisdom or experience also appreciated!
