fix problems of my website made with jomsocial

I'm looking for a programmer really expert in joomla and JomSocial to fix some translation or system problems (i don't know exactly) when my website sends subscription message, easyblog message, ecc (my website is [login to view URL]). I also propose another small job. I wanted to install in my website an extension that would allow site visitors to find or ask questions to a user registered in my website (my website is a social network for lawyers). I considered the extension Community Answers or AdsManager or another that you may suggest me.
