LFP: Looking for Pollen (Central Texas)

After 4 years of steady growth, my mystery pitaya is finally blooming! It was given to me by a neighbor when it was just a foot tall and it currently has 3 blooms about to open (possibly tonight or tomorrow).

It's a long shot but I wanted to see if anyone in the Central Texas area (Wimberley/San Marcos/Luling) has any pollen from their blooms from this year? Just in case it's not self pollinating, I'd like to try cross-pollinating at least 1 of the blooms and self-pollinating the other 2 just to make sure.

I'd be willing to pay with a 4" tropical for the trouble and could meet you anywhere in the area.

Thanks!
