I'll add some more details in and try to make estimates of how much help I'll pay for around docker.
So far I've not really used DHF funds directly for promotion though I'm giving pretty generous rates and low fees and I'm not obsessively watching the BTC/Hive rate to make sure I stay ahead. The volumes are small enough that if I'm up or down a dollar or two over a week it's not a catastrophe.
However a big part of making the service runnable by others will be keeping a much firmer hold on it being at least break even to run.
