there is a list of long arm'ers here on the board- catagorized by location- check the list, find someone in your neck of the woods- look at their work to see if you like the type of quilting they do- and send them a pm- they will be happy to send you their pricelist and guidelines- everyone is different-
some charge by the project itself- some charge by the square inch...like 1 1/2 cents a square inch-
some only do panto's=edge to edge patterns- some do custom work- some are computer guided, some are all free=handed- the prices vary as much as the techniques- and skills.
we really do not (normally) discuss prices on the open board- that is more a private message exchange.
