Patio filled with shell ASAP

We have a patio approx 10 x 5 we would like "cleaned up". ASAP preferable if we can get it doe. This week... We would like this to have one side "boxed" to contain shell (approx 5 meter width) and then filled/ covered in approx 3 cube of shell. Reasonably prepared and minor leveling required. Please Include supply of timber and shell.
