Website Help - Need a solution to a problem.

[Desmo]

We're looking at offering some web hosting to our customers so they can have their menu put on their own website. Got a reseller pack in mind so that's fine.

What I need help with is their site design. What I want to offer is one simple'ish design that their info is put into. It's going to be just one HTML/CSS page. Obviously I can change a few pictures to match their printed menu for the shop name, logo, Chinese writing, etc. But what I then want to do is have a simple way of changing the actual menu text so that each time they update their menu, it's nice and quicke for me to update their website.

Can I make up something that simply reads from a text file? If so, I can take their menu copy straight from InDesign, save it as a text file and upload. This is then read into their webpage.

The only problem I can see with this is that I'd also want to be able to pick out the section headings in another style, so how would they need to be marked in the text file. Or can this be done automatically with paragraph breaks?

I think that all makes sense....so, any ideas you pro's?
