I would talk to the person that you originally got the quote from about switching. Other buyers be aware that construction companies (don't know if this also applies to pool companies) usually charge more for work on a change order than under the original projec. This may be because they have to deliver again to the job site or change the plans and resubmit to the county or they just figure they've got you.

Hope everything works out. We are about 1 1/2 weeks behind. You can see my "neighbors" post in off topic - they have been a pain. The first inspector was late, we had a lot of rain and a cave-in that needed to be repaired.
