I don't know the situation in your country. But here in germany you can 
rent a lowend dedicated server for about 40 $/month. With static IP and 
mostly with one or more domain-names.

With such a server you can do all what you want without the problems 
coming from the dynamic IP.

Perhaps that'll be an alternative for you.
