Add some features to my brand new website

My website is working perfectly, just some areas on the website isn't working, I would like to correct those areas and add more functions to it: for example : Quantity per product. the website is [login to view URL], if you go to the Coaching Area - I would like to be able to select quantity - for example a coach is $20 per hour, I wan that they can hire the coach with maybe a drop down menu and select the amount of hours and this automatically goes to my paypal with the details. The other area that needs fixing is on the Guaranteed boosting page, "Placement Games" where it says "Current standing - Unranked" I want it to say "Last Season Standing" and to have a drop down menu where you can select the past ranks like on my other sections , I want it to automatically calculate prices by changing past rank or number of games.
