hi there
i read with interest on proposed job sets etc.
Plasterers here are two a penny and on average earn 10 to 30 usd a day. yes i did say a day.
Hairstylists there are plenty here as the women to men is 8 to 1 and its an easy trade and government fund there training.
Teaching English is a good idea , but learn the difference between English and American English. There are more opportunities in teaching British English as all the schools teach this. However, you need a good understanding of Ukrainian and Russian, handy if your wife can assist. Schools require you to speak and register as a Ukrainian speaking English teacher. But you can do privet work which needs none of the above, you just need somebody to translate for you, if your not Fluent in Ukrainian and or Russian. Lviv area you need Ukrainian , Kiev a little Russian, but Odesa area Russian is more used, but slowly moving over to Ukrainian, as to earnings, 10 to 20 usa per hour, but its very hard work as you need to teach there work books, Cambridge learning. etc etc
hope this helps a little
regards
martin Odesa
