Where to start: SN site

[alwaysbusi]

I want to make social networking site. I have a domain name picked out, and i i want to use something like Boonex's Dolphin as a template. I have 2 subsequent questions.

1) Where do i start. Buy the domain? Find a host? How many GBs should i shoot for, etc..?
2) Is there a better way to create SNs than the Dolphin program? Im not a programmer but a full time students with some big ideas.

Any help is greatly appreciated!

As far as SN, are you wanting something similar to Facebook? I think the program you use to create it all depends on the features that you are wanting your SN to have.
