Start using the position you have as a producers to move into djing. There are tons of label based club nights. Even if you don't own the label you are signed to you can still effectively use them as leverage to move you into djing.
Maybe you could do a trade off with a DJ who's looking to get into producing who's in your area. You teach them how to make tunes and they teach you how to become a DJ.
You could still go to a DJ school and learn too. The main advantage will be the equipment, it will all be pro equipment you find in clubs.
Another option is online radio stations, a 1 hour or 2 hour slot will help you grow fast by putting yourself in a live environment.
You will mistakes, who doesn't?
Just keep pushing and putting yourself out there.
I really doubt mixing will be that hard for you coming from a producers background. You already understand the principles and the structure of the music you make, the only thing that will be unfamiliar to you is the equipment you use to do your sets on.
If your aim is to do live gig's, which I'm sure it is, then you should be thinking about what equipment is already in the clubs.
Turntables, cdjs and a pro mixer (club mixer)
Ideally this is what you want to be practicing on frequently so that when you do a gig with pro gear installed your not scared of the equipment.
Keep practicing and when you talk to promoters, dj's, clubs etc use the label as your pitch to get you gigs and put on shows
