TrueStar Domains

This company (Registerfly) is having severe problems and is holding domain names hostage

I have a company that is going to start hosting and selling domain names i need to find out where to register to do that i think it might be ICANN i am not a resller and i do not want to sell my domains i’m going to be very like godaddy.com

I want to try to buy and sell domain names. How do I get started.
Could someone provide a step by step guide to getting into the business.
Can I sell domain names I buy through contractors such as ipower or do I need my own registering company?
I am willing to risk a lot of money for this business (1000-5000+).

Thanks A Lot guys.
Ipower means Ipower.com
Its a Domain Name registering company

I saw a site offering domain names for very cheap rates , is it enough if I buy those domain names alone to have my own site or do I need to get hosting also by paying extra money?

i am looking at the .biz domain names?
can i get 1 or 10 or 100 free for a year? does any one know
go to 1and1.com they are currently free for the first year
i just want to know how many i can get
that is it

This is what was sent to me
security issues we are required to combine your hosting and domain name registrations under one account.

said it would take one hour to do and web site wuld be down for that hour — it has been down now for 4 days
