How much space ?

Can anyone shed some light on how to estimate the amount of webspace I need for a PHP application ?

It will be a website with online shopping cart and ordering system using a MySQL database.

Also, how do I guess the amount of bandwidth required ?

Thanks

Rich

Bandwidth depends on a heck of a lot of things.

How much traffic will you get?
How many images?
How big are the images?
Are there big files being downloaded?

Webspace also depends on a lot of things:

Are you storing large files?
Large images?
How many?
How big is the application?
