Translating fantasy/fiction book

Job Description

I'm currently in the process of having my book published in Russia and I'm interested in the cost to have it translated into English. I know this is a broad question so approximate costs would be ok with me as I'm looking to put a budget together for this translation. I'm willing to pay for a short translation to evaluate what your abilities would be. Also I would like you to answer some question related to this project:
Do they have a track record of delivering similar types of work? There are rare situations where you may want to gamble on someone without a review history, but generally speaking, you want to see multiple successful translation projects on the freelancer’s profile which are comparable to your own project.
1. If you have done some similar books?
2. Do you have samples of your prior work?
