Hello.
If you require a website that has all the functionality like paypal then please contact. I have developed a prototype of this project and can certainly develop a secure, robust and excellent site for you. I have worked for microsoft and DHL and can provide reference to my past work if required.
Here is just a brief of the features I can develop for your site:
MEMBERS ACCOUNT SYSTEM:
Username for login
Access code (randomly generated using letters and digits)
Error messages on unsuccessful login tries
Auto session expiry with no activity on account during logged in
Security question for recovering password
Edit site options: admin user/pass, email, site title and meta tags
Ability to set date/time format
Admin can configure password length and max number of attempts
Admin has the option to protect all HTML content
currency type (USD, pounds, yens etc..) and set currency precision
Signup bonus
Set transfer fees and charges
Configure payment gateways
unlimited affiliate levels
Account Summary - view account summary for the day, current month and year
Transaction statistics (pending, completed, cancelled and refund) sort by: amount, type, status, sender and receiver

I can also add a lot more features and am available for chat should you require more information.
