You can contact the ATA , they can tell you exactly how much with additional air fare, rental cars, hotels, amenity's for the EC, ED , CHC and any of the good ol" Boys club that show up ... They like to be treated like Rock Stars and get all of the usual and customary perks as well as a place to hide from the people they are supposed to represent ... Its not cheap ... WPT ... (YAC) ...
That's not the total, that's just to the ATA besides that you have labor, targets, electric, water, toilets, and the list goes on and on ... Not cheap by any means and most clubs cannot afford to host such shoots ... If you put together a shooters choice shoot such as handicap or 16's being the primary events you can usually get good turn outs with out getting the ATA involved, just can't give ATA trophy's as if that is a big deal ... Replace ATA with the club name and logo and your off and running ... The amount you would have to pay to the ATA will more then cover the cost of the trophy's and give you a little added money for the shooters ... WPT ... (YAC) ...
