I'm looking for a company to help organise a custom itinerary in Brazil. Can anyone here recommend a reliable company?

My ideal trip seems to throw the random companies I have emailed off as it's a mixture of high-end luxury with adventure travel. I'm getting suggestions for day trips to go zip lining

I'm spending a week in Rio (Belmond) for a conference and then want to a trip into the Amazon. Being very fit and enjoying adventure sports I'd love to go to a jungle lodge and venture out from there and do some serious hikes (possibly even an overnight camping trip), followed by a visit to the Iguassu Falls.

I would appreciate any recommendations
