yes I personally would if its a company event and I have no wish to end up a Dead Hero trying to save a few bucks for my company and risk even bigger reprecussions on myself if anything screws up (even if not accredited with Casetrust, the photog should at least be operating as a registered business) .......... BECAUSE it is a business transaction .....that will hopefully/likely turn out well without any problems ........ or at least have less headache in dispute resolution if things go wrong.......
not because you get better images vs a freelancer........
But of course, different persons and different organizations with have different levels of expectations, budgets and requirements .... thus both freelancers and photog businesses will occupy their own niches in this world without killing one another.
