I'm looking for performing editions of Latin American baroque Masses. Some of the few Masses I've found have forces too large for the budget involved, which probably realistically limits things to 6 performers (either 6 singers, or 4 singers + organ (and possibly continuo.) Double choir and/or strings are out. :-)

Free scores are great, but I'd be willing to pay for something excellent.

I'm looking for something suitable for a wedding, so no Requiems.
