software dev guru. / front end

I need some dev to code feature that will increase advertisement box space. so if user pays for upgrade the advertisement box will get bigger as soon as member pays. Then i need to allow people to create ads for a fee/ sign up with account, allow ads to be favorited, and allow ads to get and be moved to the top when user wants to pay for additioanl upgrade. I need search feature, so users can search for users ads. Very simple site for a true guru developer. Dont bid unless you know you make this soon, and that you so no challenge in this task. show me some examples functions you have built. I deally i want you to work with me and have this thing completed in 3 days max. so you will be working alot of hours each day, maybe even all day for 3 days to turn this project out. SO you must know what the hell you are doing and work fastly to turn out a quality simple ad site. Needs to be responsive
