I am looking to build a site to automatically resell domains and web host space. The site will be something like WordPress, where you can optionally choose to host the WordPress app at your own domain http://wordpress.com/products/. I am looking at various hosting resellers now, so if anyone has any suggestions for a host please send them. Requirements for the reseller are 1) linux-based, 2) at least 1,500 GB to resell and 3) cPanel/WHM or WHMCS is installed. My main question, though, relates to WHM and WHMCS. Some of the resellers I've been looking at only offer WHMCS. Could anyone elaborate the advantages and disadvantages of WHM versus WHMCS?
