Advice on starting a business in Nepal

Hello everyone

This is not a new topic but the last thread about it is a little old and it would be great to have the latest tips and information on how to start a small business in Nepal.
I'm living in Cambodia at the moment but would like to move to Nepal soon and start a trekking business with a specialty. I know there is a lot of trekking agencies but I do have my clientele and I'm not worry about competition.
If anyone has experience about starting a business there: visa, licenses, taxes..etc. Please let me know
I will be in Pokhara in March/April, happy to meet anyone who could help...!
Thanks
:)

Do check it out, but to the very best of my knowledge, there are certain sectors that are completely  closed to foreigners....Trekking is one of them.
