As you mentioned that you don't have anyone in Russia to help with requesting BC again, then you might want to use some paid services.
Some of my colleagues successfully used this companycompany, but of course you can search for alternatives if you want.
Very briefly scheme looks like this:
- you give power of attorney (to request and apostile BC) to couple of representatives (employees of this company)
- they go on your behalf to ЗАГС and request BC
- request apostile
- send everything to you
Approximate costs are about 200 EUR and total ETA is 1-1.5 month
