Secure our web server from hacker sending spam

Hi someone is hacking in and sending Spam from our server. Has probably access via some clients/users with easy/vulnerable passwords. (see attached file for server log).

We need someone reliable with experience to lock this hacker out and secure our server. Make it safe again. Google and Hotmail are currently blocking email from our site as there has been too much spam/bulk mail sent out. so we will need to get his off the blacklist as soon as we can stop spam going out

This is an urgent job...looking to award this to the right person today. Possibility of re-hiring for other servers that we use and need to tighten security on

I can search the server for backdoors as well as attack vectors. If possible, I'll read server logs too. I can give advice on improving your website's/server's security as well.
