Need Sofa Cushion uphostlery shop recommendation, need custom cushions made

Anyone know a shop or person who does large custom sofa cushions? I need a very large cushion made from scratch for a sectional that would be about 7ft long and 3 ft tall, 6 inches thick and a smaller one to go with it, maybe 2ft x 4ft long. I am on the Northside, Kingwood area.
