I think this is the right forum - if not just move it:

I have been asked to design and produce a website for a friend's dad's Self storage business.

He is willing to pay me but I have no idea how much to expect - how much is not enough and how much is totally to much;

I will be producing:
About 10 - 20 pages of information,
most graphics apart from the logo, such as bullits or buttons ...
and regular updates.

got any suggestions?
