Ensure in your contracts that your liabilities are limited to the discovering and online hiring services. Your contract needs to ensure that you do not portrait yourselves as an event company. It has to be clear in terms of obligations and services that you would be performing and who shall be held liable in certain events. Finally, ensure your contract is not one sided, or you may invite the wrath of court for "contra-proferentum" should there be any litigation round the corner.
thanks.
