More than 3 Guildhests?

[Galacia]

My highest class is lvl 43 and I only ever unlocked the first three Guildhests. I've tried visiting Lost Rabbit and Ribald but neither offers me anything except what I already have. How do I unlock more?

Completing the ones you already have should unlock the following guildhests in DF

I've done all three many times.

I've done all three many times.

So, as it turns out, I never did the first lvl 15 guildhest. I thought I had, but I just did it for the first time when I turned 15 as THM. And of course, once it was done, the next one unlocked. So thanks to all who replied and I apologize to ZanderMist for prematurely rejecting your correct answer.

Just a FYI: Guildhests up to the first level 30 one are likely to pop fast, as that far is required for 2.1 storyline to be completed.
The remaining ones pop now and then too, but are likely to take much longer.
