I have never hired help myself because I have not had the need for help so have no first hand knowledge of all that is required.

IMO it is important to remember that you are a BUSINESS and therefore the rules for hiring someone are different than if you are just hiring a 'occasional teenage babysitter' into your home and what not!

Before doing this I would check with your insurance carrier that an 'employee' is covered under your policy in case they are injured or hurt on the job because my understanding that is different liability coverage than if an 'client' were injured.

As well as if you are in Canada what the rules are for being an 'employer' regarding taxes because employees regardless of being part time, contract, and short term are entitled to minimum wage, vacation pay, CPP and EI and so forth and as an employer you'd have to pay the 'employer' contribution as well as take off and submit the 'employees' portion of those programs and so forth.

Also I have heard of providers who hire the person on 'as self employed themselves' but I would want to ensure that I had legal advice on what the criteria you need to ensure is included in such a contract that it is 'clear' they are being considered self employed and that their wage includes all the 'additional employment expenses' to avoid legal troubles for yourself should the relationship not end well and they try to sue you claiming they were an 'employee' after all and their rights were violated or something

As for places to LOOK for temporary help ~ I would post job ads at your local colleges and university and see if there are students looking to add 'work with children' to their resume!
