I will host each site for £2/month if you provide your own domain name. I am also in the business of web design and i remember when i started hosting was a daunting thing. We have a service whereby clients can submit a job for us to do e.g setup a new account, change a password, etc etc or they can do it themselves via a simple control panel. I feel this would really help you and would take the stress out of hosting for you.
feel free to drop me a bell with any questions you have either via my profile here or via the website at

hope to hear from you soon.
kind regards,
