Very few photographers here on MB will ever pay, photographers work for 3rd parties and these 3rd parties pay.
Stock photographers should pay but there are very few that actually make any money.
Its a catch 22, the established guys you should be working with will not approach you and the guys wanting to build their port will normally not pay you.
you should assume any approach to be one based on TFCD unless stated otherwise.
You got a good look and should do well, if you don't like someone's attitude just move on (in a nice way).
