Hi. I'm fluent in Hungarian (Jo napot kivanok. Angolul fogom folytatni az uzenetet, mert nincsenek magyar betuk a billentyuzetemen; de ha felvesz, nem nehez installalni) and an experienced web programmer, but I'm new on freelancer.com, so I'd be happy to translate your plugins and modify your site for $5/hour and a nice review at the end :)
The job, as per your description, should take me 3 hours. So that's a fixed price of $15.
I work with modern standards (html5, css3, JS libs), so everything I add will look modern and fit in with your site. Please, contact me to discuss any further details. Looking forward to your reply,
Alex
