Jared -- Can you explain in detail how a two-B-channel transfer would prevent Rafael from having to pay for so many minutes? The calls are terminating to a phone on the PSTN; you'd still have to pay someone for the originating leg and terminating leg. You're just taking Asterisk out of the middle once the two legs are up. While that allows you to handle more calls on Asterisk, what I understand is that you are still paying for the two legs. Beckman On Tue, 15 Sep 2015, Jared Smith wrote:

With all of this in mind, I'd like to know if anyone here has done a similar project and would be willing to share their experience. I am trying to accomplish everything with the minimum amount of resources as possible (money and DIDs, etc).
I helped consult on a similar system eight or nine years ago -- at the time, my client used Asterisk with PRI channels instead of SIP channels, because of the ability to do a two-B-channel transfer and cut himself out of the middle of the call after the connecting the caller to the called party. Asterisk can initiate the two-B-channel transfer, but as far as I know doesn't yet do anything with the message coming back down the PRI letting it know when the call has terminated. (Well, that's not entirely true -- Asterisk logs an error message, so I assume it wouldn't be too hard to actually connect that up to some sort of better logging to be able to determine the call duration.)
It may not make sense in your situation, but I thought I'd pass that along as one way of not having to pay for so many minutes.
