Use virmiculite with water, 2:1 by weight.
Hopefully the eggs have not attached to each other, they are easier to hatch if you can separate them.
Do not turn them over.
What I did ages ago - ceramic bowl, with the mixture, make depressions to put the eggs in, put suran wrap over the bowl (it should NOT touch the eggs) but have a few holes poked in the wrap.
Put a thermometer in the bowl, temp should be ~ 85F or so.
I used a light bulb to warm them. Watch the temperature.
Twice a day I would lift the suran wrap to let it breath, and if the eggs started to cave, I used a spray bottle with pure water to remoisten the vermiculite.
This worked extremely well for my lizards and turtle eggs, worked so so for my snake eggs (only about 50% hatch ratio).
If you can afford a real incubator - buy one, but do something like I suggested soon so that they don't die while you set it up. Watch the temp closely so they don't get too hot.
Big Apple herp has some incubators you can get mail order via their website if a local supplier doesn't carry them. But you need to do something soon, even if makeshift, or you'll lose the clutch.
Don't turn them over. You can get vermiculite at any garden store. 2:1 by weight with water.
Oh - I haven't bred for years, so if someone who has says something different, trust them - not me.
