456631 Modification of MySQL db

I have an existing website which I am looking to change some php features on it. It has an existing database but only one login where I need there to be two logins (another field in the database with a 0 or 1 to say which user type it is - business or private) There will also be a payment to join (preferably before registration page) there has to be a redirect to a paypal page for the person to pay to register, Change the list of cities and towns to the a of locations and areas I have already congregated. I would also like a search map where you click on the area and it searches also. 99% of this website is complete - I just need a quote for the above please?
