who can offer the best price on cpanel licenses or hsphere licenses?

Try to contact the owner of FluidHosting.com, dave@fluidhosting.com or Jim@fluidhosting.com.
As far as I know their hsphere licenses price is very competitive.

Good luck.

We buy our licenses from NixHosting here is a link to their cpanel lic page. Support is super.

Daniel P from effectonline and Robin from myvirtualnet distribute cpanel licenses. You may want to see if you can get some good prices from them.
