Well you already have PT LE so if you can find one of thoses $600 002's that someone else mentioned, you could spend another $500 and send it to get modded by Black Lion Audio:

I've heard amazing things about their work. So thats one route to go and with those projected numbers, it would still leave you a few hundred bucks to buy some sort of preamp. Up to you though. This is just another option and all the other ones presented thus far sound like they would work great as well. Just depends on which route you want to go down.
