Besides teaching English like ecocks said, which can bring you in around $1000 a month plus a free apartment, your management experience is in high demand in Ukraine. There are numerous job search engines for Ukraine, some in English and most in Russian. However, if you have your wife look at these pages and just type english into the word search, you will begin to see what kind of jobs are available that desire strong English knowledge. Management type jobs, besides computer ones, are the positions most sought after for Expats. Some require Ukrainian or Russian knowledge, but some do not. If you have any computer experience, the company I work for in Kiev is hiring technical support supervisors that speak fluent English, and they are getting hired at 7500 hryvnia a month ($1500).
http://www.rabota.com.ua/http://www.ajob.com.ua/searchvac/http://job.bigmir.net/searchr.phpThese are just a few of the many job search sites, just put in the city Kiev, and english in the word search. Also, companies in Kiev will be more willing to hire a foreigner when they know they are going to be living in the city atleast several years, so be sure to mention your wife and your situation, it will go a long way in the hiring process.
Also know however, that in many cases, a job might not be secured until you actually arrive in Kiev, as many companies are hesitant to hire someone that still has to travel to the country.
