I can help you out, however can you please notify my roughly how much space / bandwidth you would need?
I can kind of give you a jist of what I can offer you:
10GB Of Disk Space
100GB Of Transfer
Unlimited MySQL, e-Mails, FTP Accounts, Subdomains, 20 parked & 20 addon domains.
I can't give you custom nameservers, however I don't see why you would need this for an individual shared site. A simple tracert will show the server you are on.
