How much can a successful reseller expect to make (profit) monthly? I'm not asking for personal bests or income, just rough ball park figures if anyone is willing to talk numbers.

As soon as you start you will have red line. And then all will depend on your marketing skills. Web hosting related issues will be taken by your web hosting company. There are no extact period of time guaranteed.

It depends on your personal contact and marketing skills, if you start locally, you'll find it is easier to start with but as said by "ServerPoint" there are really no exact period of time guarantee.

I think it depends on alot of variables. What you consider successful resale figures, etc. With some reasonable invested marketing and advertising time friends I know easily make a couple hundred a month up to alot more for people who want to replace their income with their reselling and spend more time and energy on it.

A few hundred dollars profit target to begin with and a few thousand dollars when it becomes your full time job !?

You can make millions, sky is the limit. But not as a reseller. Start with reseller first and as your customers grow get your own servers. And that way your business will and so will your income.

I think that theory and practice are 2 different things.

You've got to spend money, to make money.

You need to devote a significant time too

yes, it depends upon you marketing and planning ...

I would assume this will depend on your reseller account specs. But that could be from $100 to thousands.
