Orion, I know it can be very overwhelming, trying to train your dog, and finding help to do so. Not only that but if and when you do find someone, they may not be terribly good or knowledgeable or worse. Not many actual pros will help you on evenings and weekends, as has been said, to fit around your work schedule. Many will, however, accommodate a paying client who leaves their dog, at least thru the FF process, and then meet up for training sessions afterwards. Mine do. We get together on weekends, holidays, some evenings. Not every evening, not every weekend, pros have lives too, but enough to answer questions and keep you going in the right direction. Some pros also leave for the winter, something else to ask when you start making calls. Some trainers may do private lessons that could work into your schedule as well, but expect to pay more.
I don't know your area as far as making suggestions, but, go to entryexpress.net and look at hunt tests and field trials in your area/state, probably have to go to the HRC site to get most of the HRC stuff as they don't all use entryexpress. Or NAHRA or the other organizations. Or even take a look at the stud and litter ads, if those people have any kind of titles on their dogs, they might have some training contacts or pro referrals. Find those clubs in your area/state, contact the committee members listed and try to get some references and suggestions there. Have patience and don't get frustrated or turned off, there are people who will help, you have to make the effort to find them and be willing to give in return. There are lots of little groups and people all over the place going about their business training their dogs around their work schedule and family life. Might have to dig for a while to make connections, maybe prove you are willing to work and stick it out, sometimes people are tough on noobs because they've wasted a lot of time in the past on them with no return, but once you find a pro or training partner that fits, it's a lot of fun and tremendous help.
