I'd like to see myself with the same trainers for an amatuer or pro career. I don't think I'd choose to change trainers just because of the move from amateur to pro because success in either arena is based on having good skills and development.

Sure a few skills are more or less important in the pro game than the amatuers but I tend to think someone who can really coach you for one well should also be able to coach you well for the other too.

I've always found that if I have to change gyms it's been easiest at times when I'm also moving geographically and that isn't so uncommon. That's been a good way to get myself out without ruffling any feathers for the most part or having to say why.

I don't think a year is a long time to be training before your first bout. Often those who take a little longer to train before their first bout have a much better time in the sport so don't worry about that. I started too early - 2 months after my first boxing training - and I don't really recommend that.

I am going through a phase right now when my studies are keeping me too busy to fully apply myself the way I'd like to my training. So I guess if I expect my trainers to be understanding of that I also have to be understanding of them when things come up in their lives and i'm not getting enough coaching for a while.

Having said that I'm not sure where you draw the line. There has to be a point where you need to put your safety first and if you really think you're not being developed enough for the bouts you're entered into by the same coach then I'd cut and run.

I sometimes think my coaches would put me into any amateur bout without having any idea how my skills or my physical shape has progressed. They might put me in for sparring a few times the week of the fight and watch in case they want to pull me out at the last minute but don't seem to pay much attention for months beforehand.

The assumption seems to be that any bout will be good for my development and my fitness should pull me through if all else fails. Ultimately I'd feel more comfortable with a roadmap to follow so I knew in myself I'd improved since my last bout. Perhaps they don't enforcce that because they know I like to make my own maps though? Perhaps it's a case of be careful of what you wish for?

I don't know if I'd change the trainers I have now but I think in many cases you don't need to make these decisions because you'll find yourself relocating for work or whatever and have to change anyway.
