He is asking for WHM Reseller software which means a Master Reseller. It is very rare that a good host will offer you WHM Reseller. I would recommend getting a VPS if you plan to sell Reseller accounts. One level of reselling is more than enough, after that you just lose control (think abuse / overload etc)
