I suggest you make an enquiry to both SCI and The Hunting Report. They maintain an extensive database of outfitters and PH's, with actual reports from clients, both good and bad.
If not a member, you should join SCI anyway and the grief a subscription to The Hunting Report can save you is worth many, many times the cost of the subscription.
Unfortunately, there are many scammers in the safari industry and it is to your advantage to find out before you book and pay your money.
