Sounds good. Much better to go with an organised trip than trying to find the wildlife yourself! Also safer, seeing as you'll be carrying camera gear worth a years wages to the locals. I spent some time in the jungle in Bolivia. Be prepared, when they say basic, they're gonna mean it!
We had water (from a pump well) but no electricity! An amazing experience I'm sure you'll remember forever. I'm smiling remembering as I write this.
I like the sound of some of your payment going towards nurturing local peruvians talents. In some parts I found locals on us$50 a month

So no way they'd get the oportunity otherwise.
If it's right for you, go for it!
