Facebook Competiton

Hi We have a facebook fan page and I want to run a competition. I want people to have to 'like' our page in order to enter their name, company name and email address to enter the competition. I would need a database of all those leaving their details. I also need the people who already like us to be able to enter the competition. It would be good for the new 'likers' to be able to refer a friend as well. I also need someone to design the competition page - I'll provide all the graphics and wording. Obviously I need to be able to make changes if it's not quite right. Then I would need you to load it up on our facebook page for me. I need you to show me examples of your previous work on facebook - anyone submitting a bid without examples will not be considered. I don't want to spend a lot but I am looking to run approximately 6 competitions + a year so if you do a good job then it will be regular so please think about your bid before posting. Thanks and look forward to your bids.
