You say your site has not been built yet. Are you looking for a company that can build your site, or for software so that you can build it yourself?
If the former, I'm sure quite a number of the readers here would be able to help.
In case you want to have a go at it yourself, CoffeeCup has two progs, The HTML Editor, which is assuming that you have some knowledge of HTML, and VSD which is not assuming anything, and is easy to work with once you have read the basics in the manual.
As to replicating your site, you can open and edit it to suit one of your agents and then save it under a different name and in a different folder. If the agents only need one page each, you could just add pages and copy over the layout from your own pages.
