Fix a tech problem with a wordpress site

Hey, since the latest wordpress attacks i kind of lost the site [login to view URL] - an online magazine held by volunteers we had running since some years now. I know very little of tech stuff so I cannot fix it by myself...but as I can see all the posts still are in the database, i believe it shouldn't be a tremendously hard issue to solve. Once awarded the project, freelancer will get full ftp access and access to the database.
