Competition entry and referral form

I need a basic competition entry and referral form done. The form can only proceed once 5 email addresses have been referred. The form is exactly the same as this example. <[login to view URL]> . Content to be saved to a basic admin system in date order (from newest to oldest). Admin system to search and filter all content in Alphabetical order and by Date. Email to be sent when an entry to the competition is made. The hosting account is with <[login to view URL]>
