If you are still looking for a guild, The Elders has room for both of you!
The mins are only 60k/600s/40t so not high for your wife to meet, while most members donate more along the lines of yourself. We hit 35k seals regularly so with both of you in the guild, 40k could become more common!
If you have already joined a guild, I understand! Just thought I would give you another option.
