Vivaldi Gloria instruments

My church choir is undertaking the task of performing the "Gloria".  We'll be using instrumentalists from another church (2 violins, viola, cello, oboe, and trumpet) as scored.  However, I don't really have an instrument that will fit the bill for the organ part on Mvt 8, Domine Deus.  Our tiny budget is about shot so renting an instrument is most likely not feasible, especially for only one movement.
If anyone else has run into this predicament I would welcome your suggestions on how to perform this particular movement.

The original scoring for the "Gloria" is 2 violins, viola, 2 oboes, trumpet and continuo, which includes cello, bass, organ or harpsichord, and other bass line instruments you might come up with--bassoon, lute.  There is no independent organ part for any movement.  I just looked at the IMSLP score and whoops, there's an organ "part" for that movement--it's a written out continuo part.  The solo part of that aria is for alto and continuo.  In any case, you need a keyboard player for the whole piece, not just one movement.  Does your church have an organ at all?  More difficult for you may be finding a good continuo player.  Where are you?
Good luck!

You could always ask around and borrow someone's electric keyboard, set to the "harpsichord" sound.  Some of them can be convincing enough to get the job done.

Electronic keyboards nowadays sound much better than they used to. A few caveats, though:
If you use a harpsichord patch, make certain it plays in the correct octave (i.e., C4 sounds C4).
"Church Organ" patches on synths are usually "tutti" sounds sounding at pitch, at least 1 octave above and one octave below. If you choose to use that sound for some places, play everything up an octave. "Combo" or "Reed" organ patches won't work for this rep.
Try flute or even "ocarina" patches for the quieter movements. I've found both to be useful in various situations. ("Ocarina" may need to be played up an octave as well.)
However: for any Baroque (& many Classic era) work, the keyboard is essential throughout.
Hope this helps,
