I would like to hire a Sewing Expert

Just need a one-time sewing job done. The project is to make a new liner (of the same dimensions, design, etc.) for this pet bed. Two zippers will be removed from the original liner and sewn onto the new material that I will provide. I have yet to buy this carrier/bed because I would like to know the possibility of altering it first and how much it might cost me. Start 15th of Nov
