i'm looking for a script that would allow restaurants to post their menu and take delivery orders online. it should be setup to take payments online as well.

i've been search for a day and have only come up with one that is downloadable, most seem to be services to use on their servers. it doesn't have to OSS, will pay if the script seems worth it. i'd also hope that it would be open to customization.

i know that i could program this, but client doesn't have that much of a budget so i'm looking to see if i can cut some costs by building on something already done. i know i could probably use a simple shopping cart script as well and modify it - but i'm looking to see what's out there.
