Outdoor Canvas cushion bags

I understand that you need someone to sew some canvas cushion bags. I am located in San Diego, do you have the fabric and will you send it to me with your design/measurements/requirements? Do I need to pick up fabric? What time frame do you need these sewn by? How many do you need to have sewn? I have done quite a lot of upholstery/re-upholstery work and am familiar with heavy fabric and strong seams. Once I have the instructions/design/measurements and the fabric--depending on how many cushions--I could have it done in a few days on my sewing machine. Will they need to be filled or just sewn? Please write or call with further details I need. Thank you Alicia
