Audio uC Development Board

I'm interested in making a audio out device.
I'm not sure of all the microcontroller port types I'd need to
accomplish this. I'd imagine I'd need 2 D/A Converters at least.
Does anyone know of any resources to connect all these circuit elements
up to the uC as well?
I'm considering d*** since it's cheap and many support DIP.
In addition, what's that name for the headphone jack for purchasing on
a store like mouser?

Also I'm just curious. It might be that PIC may not have enough for
what I need, what would I do if I needed to make a PCB that uses
something like a LQFP package microcontroller on it? I can design the
PCB but I can't solder the chip onto the board myself is there a
service that'll put the chip on for me for a decent price?
Also where can I find a place for enclosers as well?
