Pro's and Cons in both. How much should I set aside for design? Ive gotten two quotes of under $500 it sounds like a good price or is it to good to be true? Merchant account is already setup and authrize.net is the gateway. Thanks for your help.

How much for design? $77.42, and not a cent more!

Of course, it depends how *much* 'design' you want. If all they're going to do is change the button and template images and alter the css colours, then I'll do the 'design' for you, and charge far less ;)

If they're going to rewrite all the pages to display in a non-obviously oscommerce style, then $500 seems very cheap.

Both zen cart and oscommerce are authorise.net enabled from the start - its a 5 minute job to enter your details.
