There are many teaching agencies out there all charging different fees and offering benefits to register with them. You may want to try and use one that has been recommended to you. If the agency asks you to pay a fee upfront to register with them, you may wish to ask for a two week free trial to see how they work before committing.

A good agency will not only help find you work in the areas you wish to work in but should also support you in terms of lesson planning and material and emotional support with difficult situations. They may not have staff trained to deal with giving advice on specific circumstances but they should be able to point you in the right direction of someone that can.

Many agencies only charge a fee if they find you work, make sure you know what this fee is upfront so there are n nasty surprises in your first pay packet.
