So here is what I do when looking for an outfitter for a guided hunt, I hope you find it helpful
First I do an internet search. You would be surprised at how many OF have webpages that are 3-4 years out of date. Please, keep your website current. you will reach many more people this way than at hunting expos, which are probably the next best way.
Second, I look for pricing on said website. If I have to "call for pricing" (sound familiar?) that means it is too expensive. Why would an outfit (or any retailer for that matter) not list the price online? Are they ashamed of what they charge?
Third, I look for current pictures, and they should show all the animals taken not just the monsters. Assuming the clients don't mind.
Fourth, I look for references, now usually with emails, so I can contact previous hunters.
Fifth, I like to call and chat. Please return my call. And not at midnight, be mindful of time zones. And if you are away for the summer/winter leave an alternate phone number for that season.
And last of all, keep track of your previous hunters so if you suddenly have an opening you can call me up to tell me that and guess what maybe I will take you up on it.
Good luck with your new business.
