Salesforce Joomla form integration

We have a Joomla website and form. The form is currently integrated with SugarCRM. We have moved from SugarCRM to Salesforce. The website form currently pushes: First Name Last Name Phone Number Organization Where did you hear about us When would you like to schedule a demo Note The webform create a custom download link and send me an email with the link. If all details are right I manually send the download link to the user. When the link is clicked by the user SugarCRM is update with the date the client initiate the download via the link. Currently all this is working in SugarCRM We need it moved to Salesforce. We also have some other small jobs for Salesforce if the coder delivers quality code.
