Hello,
to put it plainly, there would be no problem for me doing what you ask for (a proof of that can be seen on my reviews feed, on one hand, and I can always do you a sample if you ask for it). I have done numerous jobs like these, on and off freelancer.com platform, so I don't expect any issues, though one thing I always aim at doing is that a pre-handshake assessment at least of a substantial portion of the original text the work is about. So, if it would be possible for you to provide say a paragraph from each of those five pages, for a preliminary assessment that would be greatly appreciated.
One thing I would like you to clarify on though are the source and target languages, because, on the job brief, on the title line you say "5 pages Bulgarian to English", but then later on you say it's targeted at the "Bulgarian audience", and on "Skills and Experience" bullets you say "proven experience of translation ... from English to Bulgarian", which is confusing/. Either way it's fine, just need to know for certain.
And it would be good to know proper word-count (no need to be extremely precise number though) to make sure the job is properly, and fairly, priced.
I am readily available for working on this, and the second day is mostly for at least two rounds of proofreading, which I usually do before submitting my work.
Kind Regards,
Dobri
