Looking for programmer who can build a design tool for online store. I sell promotional items and I need a program that can custom their designs for print I would like it to be similar to -->[login to view URL] I cannot spend much, if you have a clone or premade design tool, please contact me with a price to fit my budget. ANOTHER OPTION: Perhaps, if it all possible that the design tool can (create a general idea of product) basically, how it would look like and then the design at completion can be emailed to my graphic designer so he can (perfect the design) that the client created with the design tool. IM Not sure if this method will be more cost effective? If so, PLEASE Let me know what you can do for me?
