Does anyone know how to begin getting prices for retail space for rent in the BTS station? I went to the BTS website and it said a company called VGI handels their retail spaces but no phone number and serval emails all have gone unanswered.

There is contact info on the VGI site which includes phone numbers. You might give that a try.
