Hello, with over 10 years of web development experience which includes fixing hacked sites I can certainly help with this. Although not an easy task most times the site can be fixed but there are times if you dont have a clean backup, you may need to rebuild in which case, this bid would have to be revisited.
Just so you know, if that were the case, any money from this bid I would credit towards building the new site IF it comes to that. I would let you know asap if I think it can or cannot be fixed.
I am also available to skype of phone chat if needed.
Thanks for your time,
Chris
