It is something we can offer - I'm part of a film making team that also does YouTube videos.
However if your going to be making regular content then I'd be more then happy for you to make it the best you can (this is likly to be the most cost effective)
At the moment YT is all about making regular content - if you can create something that you can put up once a week or once every other week and gain a following you will benefit from it alot more then putting up the occasional vid (its just like building a brand, think of subscribers as your followers)
You could easily put up a 2 min video, focusing on one part of your technique on a weekly basis (not something I know so lets keep it simple of week 1 upper body, week 2 lower, week 3 cardio, week 4 tricks for training at home, week 5 diet tips.)
If you could link to either yours and/or your competitors I could give you more information on the shoot style, equipment ect....
