WP THEMES PLUGINS WIDGETS

I’m making a web design company that designs and builds the sites and I want to host the sites that I’ve build on my own website. How would I do this? I don’t need anything complicated, just hosting with a domain name. I need it to be FREE, but I’m willing to pay under £30.
Please can anybody help?

What do you think would be easier to sell web design… by opening a web design studio (if a client comes start the design from zero) or by creating a templates site where if the clients like any design they can just download it at a price?

Tell me, what should be the common and Best Suited hierarchy for a web design Team ?
