Hi there, I'm Matt Sergei (do call me Matt, please), native Slovenian and this is the honest and best quality rate you will get:
0.04 EUR/word or 10 EUR/page (page = 250 words)
The usual freelancer rate in Slovenia is 0.09 EUR/word and for agencies from 0.15 EUR/word (only for the first project for a new client, then 0.25 EUR/word).
I don't have to state my references - over Freelancer I have been leading a large website portal translation with 1.5 million words and was a leading translator of Freelancer front end to Slovenia till recently (because there is not a lot periodic work anymore). As technical writer, webmaster and IT developer I have no issues translating technical texts, keeping HTML5 markup and similar features to take care of.
For a quality translation 1-1.5 page per hour is usual, with 8-10 hours daily. So up to 10-12 pages daily.
Regarding the above I will NOT accept hourly rate (you can open a new project). It can quickly become unfair for a client, especially when you work with slower freelancers and/or complex technical terms.
Looking forward to your reply and hope you are safe,
Matt
