Now that you seem to have made a decison, my 2 cents worth (or not!)
If I were buying a handmade item I really would like to see and handle it first. The quality of knitting varies from one item to the next, one knitter to the next. If I were selling something I would want the purchaser to be able to see and handle it for the same reason. If it's been inspected, they really know what they're getting. Maybe if you made some things up you could get a stall at a craft fair. Here in my town there is one every year before Christmas. There are many possibilities.
You can't knit the left sock first. Ever.
