What is the going rate ($) for an architectural survey of a 1-story commercial ...?

The money could range from hundreds into the thousands. It all depends on the person, their credentials and how long they will be there for.

Your best bet is to call around to some places in Staten Island where advertised and then check for costs. Alternatively once you have checked for the costs, you should then research the people that you are thinking about going with, checking with the better business bureau to see whether they have any outstanding complaints against them.
