Boat canvas repairs

I have a favor to ask of all boat owners that have had repairs made to sail covers, biminis, dodgers and the like. I have a friend that is a meticulous worker and she has been repairing canvas boat accessories this winter. Resewing worn seams, replacing zippers, patching holes, reinforcing grommet holes, replacing webbing, etc. She is concerned that she can't charge enough for the time that it takes to do a perfect job. Will the members please post for me the types of repairs that they have had done and the cost of those repairs and how satisfied they have been with the service. Thank you all very much.
