I do agree that creating a temple to Shallya is a fitting way to spend the money, but I disagree with the "no priest" thing. We build and consecrated a temple of Ranald. We spread his word (not successfully that time with the watch, but we tried). We just held a service to Ranald, probably one of the biggest out there. We are a priest by pretty much any sensible standard, except perhaps an explicit command by Ranald to priest at people. But that's more like the level of prophet, not normal priest.
And I'll point out that we have received a vision of our god, followed by a divine artifact symbolic of all his facets, which incidentally can function like a supped-up mobile shrine. So I'm not sure you can get more Ranald priest than we are. Maybe by going to the priest club and having all the other priests go "Such Priest! Much piety." but I feel like that's doing it wrong.
