I am an Australian developer of Zen Cart online stores with more than 8 years experience in this field. I commissioned my first web server as far back as 1996.
I am very active on the Zen Cart forum, nickname frank18, and have written a number of plugins for ZC.
I have been maintaining an online store for the Australian designer, manufacturer and wholesaler Sun N Sand Pty. Ltd. for many years. This includes upgrades, setting up specials, clearance sales, adding new products, updating prices etc etc.
Choosing an Australian based designer will give you peace of mind
