By "help with translation", do you mean you're looking for someone proficient in both English and Russian or do you want a proofreader who can catch grammatical and spelling errors? Or some combination of both?
TY! After you responded I found this app called Translator++ that's supposed to help RPGMaker devs easily translate their games. It's AI translation though, and the newer versions are paywalled, but maybe it could be a temporary tool? At least until you're able to find a real person who can help.
