While you're at it, you could solve your dynamo wheel problem with: http://www.ebikestop.com/quality_wheels_pavement__front_wheel_650b_32h_shimano_dynamo__velocity_synergy__dt_competition_all_silver-WE7273.php
I've had good luck buying the Quality wheels and then going through and doing the final tensioning, stress-relieving, trueing myself at home. Think of it as buying the parts, conveniently assembled into a wheel that has been mostly completed, and you just have to take it the final step. Even if you have to pay someone else to do that final step, it's almost certainly still cheaper than having a wheel built from scratch. As to cheapo parts. Like you, I can't afford to spend too much money on parts. But I usually try to go for Shimano 105 / Deore type quality, which seems to be usually the optimal compromise between "good enough" and "not too expensive". My experience with cheaper parts, e.g. Shimano Soros, was disappointing. Maybe take a look on EBay and you can find new old stock that'll save some cash but that you don't have to worry someone crashed it and they're hiding the damage. You're going to be riding this bike a lot of miles, both in training for PBP and on PBP itself, and hopefully for many miles after, so think in terms of cost per mile. The last thing you want is to spend $2000 on airfare, hotels, etc for PBP and then end up sitting in the middle of France, unable to proceed because your $25 derailleur broke at 3am in the rain and you can't fix it well enough to get to the next control.
