Sounds pretty typical. Make sure that Colorado spa is UL/ETL listed, I think it's required by law. Or is that just in certain cities?
Have the electrician pull the permit, and pay for it. If you do this instead, then all onus for inspection falls upon you. If the electrician pulls it, the inspector works with them.
Usually at least 2 inspections are required. One rough in, and a final. If you can arrange it, don't pay in full till the final inspections is signed off.
