I have the same problem that you faced. I met him last week to discuss the floorplan and it took close to 2 months to come out with the quote. So I guess you have to be patient abit.
He just fly kit 3 times right. That's not too bad. See mine:
First meeting, end Dec: Gave him the floor plan to quote.
Second meeting, mid Jan: Didn't turn up, did not answer call.
Third meeting, mid Jan: Didn't turn up, will arrange weekend.
Four meeting mid Jan: Didn't turn up. After that, couldn't contact him.
Five meeting, early Feb: He forgotten, will arrange the next day.
Six meeting, early Feb: He lost the floorplan so cannot meet, got to find the floorplan.
Seven meeting, early Feb: Finally meetup but no quote because cannot find floorplan. Give him another floorplan.
Eight meeting: He lost the floorplan again but luckily found on the same day. He wrote the quote on the spot.
Just to let you know that currently he is handling several projects at one go so he is abit up to the neck. If you are not in the rush to renovate, give him a little more time.
