It is impossible to recommend tour operators, it is not allowed on TA.
But there are some people who travelled to these countries, and you can contact them directly by private message. jeanmorrison is a name I remember. She can give you information:
Take into account, that in Bhutan and Nepal, your tour compnay has to use a local agent, so you might do it better by yourself, finding a local agent in every country.
Welcome to Bhutan Forum!
I have been to all these three countries through an agent based in Kathmandu, a genuine person and very helpful. I am currently living in Nepal as I am working for an international organization. All these three countries are amazing and I am sure that you will have great time here.
Personally, I think as per the TripAdvisor guidelines it is allowed to post recommendation by genuine travelers. I just sent you a private message, please check it.
i think if you put your query in Nepal forum you will get alots of useful info.
yes you got already some useful info and i want to suggest you to find some good company in Nepal and talk with them, i am sure you will get alots of idea what to do.If you are interested with any company you can book with.
if you want more information please send me private message.
