building a postfix/spamassassin filter box in front the MS Exchange server

We got a lot of emails that are spams. We heard the spamassassin with Postfix can be good to block the spams. We like to hire someone to build such a box on Linux. It will sit on the Internet to receive and send emails. Exchange server will stay behind it. This box runs Linux 2.6 kernel code on a PC, best solution will be use OpenWRT as the base, with PostFix, Spamassassin, ClamAV, Popfile all configured in. Finished project should have a basic like OpenWRT build environment so that we can put on any PC running Linux, do a make configure, make, and make install sort of method to rebuild everything. In this way, we don't have to hire expert each time we get new server, or each time there is a new release of postfix, spamassassin, etc. Please let me know if you have any question or suggestion on this project.
