joomla registration & custom form

We have a joomla website with custom template. We need to have a "register now" button, that leads the user to payment options (currently paypal). Once user has made a successful purchase he needs to get a receipt number in an email, as well as a link, that will allow him to register on the site. To register he needs to enter, full name, email address, contact phone, password, password confirmation. receipt number. a link is sent to him email address for verification purposes. a receipt number can only be used once to register a username. User then has to log into the member area, where he needs to fill in a web form. the html for the web form is done. you will need to write the php code to insert the data into a table. there is a picture that needs to be uploaded to the site. the picture must get a unique name that is directly related to the data the user has entered. We need this work done right now! First line in your bid must say: Namaste! You are required to code and implement everything from the landing page for the registration (that leads to paypal page), all the way to the successful submission of the form to the DB. Max delivery time 24 hours. We are working on GMT -4. Only bid if you have experience in PHP, Joomla, Paypal and registration/member modules. We can install any publicly available module for joomla, if required.
