That's a lot of pins.  You could be a little less ambitious to start.

No.  I outgrew bathtub PCBs in high school, when it became clear that
plating a hole was a nontrivial operation.  I've let the pros do it 
ever since.

The first thing you're going to have to do is clarify how many layers 
"multi" means.  Then add up the holes to be drilled (ie how many of each
size, and how many sizes), the total area of the board, whether there's 
anything else special needed (like gold edges, blind/buried vias, etc.),
and call your local circuit shop for a quote.

Help me out here.  What does mounting a BGA have to do with who fabs the PCB?
