editor for a story translation

I'm looking for an editor who has experience working with Russian-to-English translations.

I'm a translator who's been assigned a shot novel for translation, but unfortunately it's not really my area of expertise and I'm afraid that my translation did not reach the English language standards. So I'm looking for an editor for my English text to briefly read through it and comment/advise me on what can be improved.

The short novel is aimed for YA audience. It's written in first person, prose mixed with irregular poetic verse. The main theme is graffiti culture, Russian graffiti culture, and Russian youth problems. The translation is aimed at a British audience (desire of an author), so please edit keeping that in mind.

The text is approx. 20 000 words, the language is very simple and reads fairly easily. The timing is one-two weeks starting from 11th August.

Please let me know if you think you can help me out with this text. I'm happy to provide you a few pages as an example before you begin editing.
