Pastoral Musicians, Please Help Me!

I really need the help
of those of you who are pastoral musicians.
I tire of looking through the websites
of the publishers of pastoral music.
I've looked through OCP, GIA and World Library.
I hope someone can help me.

What is it I'm looking for?
I'm looking for a sung mass.
That is to say,
I'm looking for mass with a sung presider's part.
And this mass I'm looking for
must be in Spanish.
And not just a Spanish translation
of something.
I want something with true Latin musical style.

The only mass setting I've found
with a sung presidor part is
"Misa del Pueblo Inmigrante,"
by Bob Hurd and Jaime Cortez.
This is a wonderful mass setting
and I am currently using it.
But the truth is
this is really only a sung preface.
And while I may use this,
I am really looking for a sung Eucharistic Prayer.
Does anyone know of any?

There are many fine pieces of music in Spanish.
Misa Luna by Peter Kolar is a work of art, indeed.
Misa Salvadoreña is absolutely beautiful.
And, sooner or later, I am certain that I will use both of these works.

But for the immediate
I really need an arrangement
with sung presider part.

I'm also looking
for a mass setting for children in Spanish.
And here, too, we find a lot of good music
offered by various publishers.
But, again, I seek a mass setting
with not only acclamations
but with sung presider part.

Maybe the two mass settings I'm looking for
will end up being one mass.
It could be as such
that there is a simple setting of a Children's mass
that could also be used for the entire parish.

It's just that I find myself in a parish
where the pastor is a musician.
He love to sing and play his guitar.
And he is working hard
at developing the music program in the parish.
What a grace filled moment, indeed!

But you know,
I just can't seem to find
this that I seek.

Any suggestions?

. . . .I know, I know. . . .
. . I'm gonna hafta break down
and work with on this project with my pastor
and just create the music we need. . . .
. . I already have a Eucharistic Acclamation
for a Children's Eucharistic Prayer in head
al ritmo huapango. . .
"Gloria al Señor en el cielo. . ."

. . . . But you know,
if there's already something out there
that I just don't know about
please let me know. . .
