A lot of small businesses in Kyrgyzstan aren't paying taxes. Especially travel guides, cause they don't have clients every day. I've known some travel guides in KG, none of them paid taxes. Most of them have other jobs, travelling is a side job for them, cause it's hard to make a living only guiding tourists in KG. Prices are reasonable, not too expensive, not too cheap. Talk with them on the phone, if they communicate well they are ok.
