Have you checked out resellerpanel.com?
They have a nice system over there, a little hard to manage but it works for those who are trying to start up without any cash.
Their pricing looks reasonable.
How long have they been providing hosting services?
LiquidNet Ltd. was established in February 2003 in London, UK. The ResellersPanel program itself started on April 2, 2003. So far, more than 58 000 resellers have placed their trust in us.
Does anyone know who offers free reseller accounts?
youhosting.com does give free reseller accounts...and not surprisingly, support is horrible, performance is worse, reviews are awful, there are a bajillion template-clone resellers, everything is "unlimited", etc.
Wouldn't touch them with a 10 foot pole myself...
