i quilt my own- and those of others..turn around time depends on the quilter.
there is a list of long-armer's on the board---you can contact one in your area and ask all kinds of questions- including what (her/his) turn around time is- most of the people i know try to stay within a couple weeks- but i also know quilters who are months and years... everyone is different. i don't like having customer quilts sitting around my house- too worried about something happening---so i (try) to get them done when they come in- and out as quick as possible...but that's me---and there have been a few times when i have been over a month getting one done---each quilt is as individual as each of us-
as for pricing- that varies as much as everything else too- some quilters charge by the square inch- some charge by the quilt= some only do panto's- some do only custom quilting---lots of differences-prices=turn arounds- locations- policies.
