If you work with a RIPE LIR, they may be more than willing to help you, even if you are outside of Europe. You just need a "presence" in Europe, which can be virtual (a VPS counts.)

I am in the ARIN region but I did not want to pay the ARIN registration fees for an ASN. It was $550 + $150/year, so I went with a RIPE LIR.
