Welcome,
I am native Polish speaker and I would like to help You with your project. I have a lot of experience in translating due to my work in LionBridge Technologies. To be hired, I had to pass 3 difficult exams in English. I am on freelancer.com since 2013, and I've finished some translations so far. Most of them were websites like this one [login to view URL] with various content: travelguide, privacy policy, legal notice, apps in Google Play and websites/blogs of manufacturers and online shops. For all projects I've got best marks and my clients were really satisfied (some of them are invisible for your project). I'm one of the most successful Polish translators on freelancer.com. In last year I was awarded 43 times in 47 projects overall, as employers like quality of my translations and affordable rate per word.
As You can see I have US and UK English badges and as I mentioned on the beginning, I am native Polish speaker. I can translate your file in up to 7 days and my bid is $150. I hope my offer is interesting for You. Please also check my feeback and samples of my previous translations on my profile to ensure that I am reliable freelancer.
Regards,
Michal
