Gather data from pre-existing form page and send as auto email

Hi, We have created a basic page to collect data for lead generation - [login to view URL] We now need someone to fine-tune the page and collect the data from the 5 drop-downs we have created. When the form is submitted, the information needs to be automatically forwarded on to an email address/s of our preference. We would like the page to then direct to a 'thank you' page that we will create (the ability for a simple URL redirect will be fine). At the moment the form and data is sent to us via a clunky plug-in that we no longer want to use. We would rather it not rely on a plug-in. Any questions please ask before bidding. Thanks
