Fix Oscommerce after Hack

We need a programmer who can fix one of our clients websites after it's been hacked. We already have it running again but it still has some small issues, for example session directory not writable, htaccess which is not right ect. This website has been setup in 2006 and is an Oscommerce installation with minor code changes. Not a lot has been modified, the biggest modification is probably that its in Dutch. You job would be * Fix the installation so that it works. * Make some security updates so that it doesn't get hack that easy again. As you can understand this is a job that needs to be done quickly, we don't want the client to wait for days, so only bid if you have time to do this within 24 hours. It's an easy job for someone who's familiar with OSC and shouldnt take more than a couple of hours.
