Question About Peru Surf Tour

I am going to peru from Oct 25-Nov 5th and i have read how hard it is to get to some of the surf spots so i was looking into surf tours and i found one called peruecosurf.com. Site looks ok but when i contacted them they want 50% upfront deposited into their bank account which sounds so fishy. Does anyone else know about this? I have never booked surf tour or camp. It would be different if i could pay with credit on website but money in bank account sounds like such a scam.
