This sentence seems to indicate that you know very little about
Internet services (hosting a Web site on a DNS server...). In that
case, it would be more careful, as suggested by Fajar A. Nugraha, to
outsource the hosting (and then to spend time learning).

Back to the specific question: if the IAP (Internet Access Provider,
"ISP" is too vague) asks you money to authorize you to deploy a server
on your own machine, switch to another IAP.
