I would start by going to some of the local shows and get to know people in the area. Talk to the competitors, find out who their trainers are. You can check the NPC show schedule for local shows - there are quite a few so you should have some options of nearby shows. Use that to start networking. Talk to the trainers you'd be interested in working with. Don't get sold on working w/ the first guy who asks you for money. IMO its important to work w/ someone you click with. Also understand the cost / pricing - some do nothing but prep which is slightly different than just "personal training". Also talk about the show you want to target to get an idea of where you need to start doing "prep". You miay have time to do some 'off season'. Also doing your first show can be a whole new experience - a good trainer will help you deal w/ that but you need to commit to them to not fuck around with the diet. You either do it 100% or don't bother. Also make sure you've got someone who can help you w/ your posing. After all the work, what's the point of getting on stage if you have no idea how to pose?
Another way to get in touch w/ trainers, at least those in the area, is to contact the promoter(s) of local shows and see if they can network you to someone. Peter Potter is the primary promoter in SE Florida, tho there are other promoters as well.
And you can also go w/ online trainers. Someone I've been particularly impressed w/ is Shelby Starnes - tho he's in Detroit and currently moving out to the Bay Area... that might be too much of a long distance. I don't know what cost considerations you have, but IMO it is really helpful to have someone around to guide you thru the prep process, the posing and the "how to do a show". But also as your first show, you may discover you don't even like doing this and would be happy just "lifting" so you may not want to dorp heavy buckage. Working w/ pros can get expensive - also a thought.
As far as the juice part - just starting w/ meeting some trainers and letting them see where you are and you conveying that you have (hopefully) a solid background in training and cycling already will establish that this is part of the discussion. If you're targeting an NPC show, chances are all of this will imply that this is part of the protocol you'd like to include. You can also get more of a sense of where the trainer is coming from (and if their protocol includes juice and they produce good results ) by looking at their clients at shows.
I used to live in Broward - back in the day there were lots of pros down there, but not so much anymore.
Some people that come to mind:
Bill Wilmore (pro'd in 2005) - Bill is a great guy - I'm not sure where he is w/ personal training these days tho - I believe he trains in Ft. Lauderdale
Mark Alivis recently opened a Pro Nutrition store in Delray Beach
