I am looking a solution for make a Membership site with “Profit Builder”.
While we do not have tutorials on membership site creation, we do have a number of templates that you can use, which you can find in Profit Builder. What you would also need is a membership plugin. Sean uses WishList Member for all of his sites, though you will want to find one that best suits your needs and budget. A quick Google search gave me these results: https://www.google.ca/?ion=1&espv=2#q=wordpress membership plugin
