Two Secured Sections on Website

I need someone who can build a section of my website. I need two security sections The first one built with automatic password generation and the client can change password on first login. I need them to be able to update their information on the website in user account. This first security will give them access to a certain section of the site. The other section will be for users who are paid members. To access this section, you client will need to pay a subscription fee via credit card or paypal or check and upon verification of funds, they will receive a password and login for that section. I need this done asap. I already have the website partially completed and I need this section done and configured on the server so I can get this going this weekend.
