whmcs provisioning

My question is : I want to sell sites on a general blog domain and on either a pro-site or Buddy press domain, How do I set it up to do this? I’ve tried the Multi-domain and Domain mapping plug-ins, I have Blog-template plug-in installed to – Can’t find a way to make a template for other domains through blog-template. Bhelscentral.com is my resale Hosting account domain,which has my whmcs install on it.

I think I’m not getting something right or I’m misunderstanding the proper use of these plug-ins.

Thanks for any suggestions you can offer
