Trying to find wholesalers, travel agencies and tour opreaters to register with

Hi everybody,

My name is Adam , I'm the owner and the founder of The Resort: The Resort is a property which combines hostel and apartments , you can see more details here: www.israel-resort-vacation.com
I'm trying to register us to some wholesalers, travel agencies and tour opreaters (not retail websites , as that already been done)

Do you guys have any ideas where to start?

Thanks.
