New Website please

Hi there,

we need a website that looks just like this one:
http://tbotraining.appspot.com/

We need to be able to update it ourselves with dates and events and also be able to take payment online (we do have a paypal business account already).

Each square also needs to have a 'more info' button which takes the people probably to another page?

No budget set for this project as I haven't got a clue how much this is supposed to cost...

Thank you
