Traffic Sources for Amazing Web Hosting Offers?

I have a web hosting offer from my company which in limited test marketing to a really OLD list converted over 86% of all clicks to sales.

Now I would like to use some traffic sources, web, email, offline marketing, etc. to generate additional sales and to test our marketing before we ramp up and launch our 3x12 expanding forced network affiliate program and so we have real world numbers to show our affiliates when we launch the program.

Of course the conversions are really high right now as I am running a $200 off coupon for our enterprise shared hosting for life plan, currently selling at $299.

This was just giving out a coupon code in the email, now I have switched to making the coupon code hidden until the visitor shares our page with a like, tweet or G+... conversions should still be high and with the added benefit of sharing to visitor friends gaining more over any losses due to users not wanting to complete the

I also need to see what the conversions will be on our other offers on our shared and VPS plans so we can quote some realistic conversions on our company provided landing pages, etc.

Of course I would always like to find traffic sources which are not going to cost a ton of $$$, however if the conversions stay high on this offer and subsequent offers, paying more really won't be an issue.

Now, I know hosting is a highly saturated marketplace, I've got a niche to market and will be retaining clients at a much higher level

I'd love pointers to some highly targeted traffic from email campaigns and other traffic methods which I can plug into.


Thanks!
