I've got my own domain and have recently decided that I want to host a few web designers. The problem is, I have no idea AT ALL how to go about doing it. Does anyone know a site that could help me out? Or does anyone want to just tell me how to begin?? =P

All hosts are different, but somewhere in your admin control panel should be an option to add users. That is, of course, assuming your host allows you to do so. :P I'd check with them first to make sure you can.
