sorry, but you are neither a bodybuilder with model looks, nor a multi-millionaire, nor a famous actor or singer. So it will be difficult to attract proper ladies. I guess you will find such woman from some small village or small russian city (not capital) which has difficulties in her life to survive or difficulties with her parents that wants to leave. Maybe you should look for an orphan. She will marry you, get her education, citizenship, then be ready for divorce. After that she will find someone better. This is life. If you want some care to be cared when you get older this won't be children or wife if this wife is much younger, some money should be put aside to be able to afford care from qualified personnel privately. There could be other variant of possible future as well. You will use her innocence, beauty and health without providing her enough material means to grow and become someone in the society, will keep her at home because of being afraid she will find someone else, keep her tied to you and when she will become not so young and beautiful or gains weight you will divorce her (usually such marriages last 6 years) and will go look for another 18 year old and she will have to go back to Russia to have miserable life with not so many possibilities at that time because you stole her youth, beauty, health and possibilities with this relationship from her.
