A standard form contract is in two parts: the general portion (which applies to all transactions), and the schedule (which applies only to this transaction). Normally a business has their lawyer prepare the final copy of the general form, and then they do the schedules as they do business.

What goes where? What is needed? Search out contract examples (make sure you are looking at Canadian ones!) and then design your business' standard form and schedule for a summer's work looking after a property.
