Your bags are great. They would sell well in boutiques and specialty shops for a nice profit.
I do not know the designers name, but there is a store here where I live that is high-end. I was in there the other day for a gift for my SQA and they had some handbags made from heavy duty vinyl, the handles were airline wire with a clear tube over that, attached with crimp thingy's. They were selling for about $125 and were not any bigger than yours. Clerk said they are selling like hot cakes. They were really great and I even wanted one.
Go for it!
