Actually, getting your own web hosting company is quite easy at this day and age.
1. You can get a dedicated server and host your own services there. Try http://bestdedicatedserver.org
2. You can get a reseller hosting account. Check http://bestwebhostreseller.com/
3. Become an affiliate and promote other people’s hosting
4. Get your own server and collocate at a datacenter (this is the most tedious and most expensive). Setup your own e-commerce/hosting-company website and sell the hosting plans.

hop this is what you are looking for.

You need a good command on basic web hosting things and must have good marketing skills. When you have all this then go and find a web hosting server company and purchase a server.
After having a server you need a good website to offer services with goof payments processing and management system. You need a good support team.
