Which one is World's best Domain & Hosting re-seller company?

If you are looking for Indian Web Hosting and domain registration company, I would recommend you to go with Hosting Raja, Leading web Hosting company in India

I think Resellerclub, Godaddy, Bigrock etc. fits for you. But remember not to go with Arvixe, who is a worst company now..

there are many domain reseller company, if you want the best send message here in apsense

That was my fault. I misread the question. I was assuming it meant to resell Hosting, not Domains. ^_^ You are correct, GDI does not resell domains however you can buy a domain name through them.

I think GVO do not sale Domains or do Domain reseller business...

I work with GDI, Global Domains International. I'm a satisfied costumer, and am also an affiliate.If you have any questions about the details, I'd be happy to give you more information, just contact me.

First GVO does not allow you to sell domains.
If you want to be a domain registrar then contact me.

I like Global Virtual Opportunities (GVO). They offer one flat monthly fee for the following services:
1. Domain Hosting with unlimited bandwidth
2. Email Campaigns with Tracking
3. Unlimited Auto Responder Package
4. Prospecting & Lead Generation System
5. Affiliate Marketing
6. Internet Conference Rooms
7. Complete Video Producing System

Everything is in-house, no third parties, so they pass the savings to you. I use GVO and love it.
