So your first order of business is to get an incubator. Check your online classifieds for cheap mini-fridges or wine coolers. If you can find a broken one even better. Get some flexwatt, a herpstat, some incubation medium, and a nice size tub that will fit in the incubator and will fit a good size clutch of eggs. There are quite a few how-to's on making incubators. It is really easy and much more cost effective than buying one.

While the eggs are incubating, try to get your hands on a hatchling rack (or make one!) so you have space for the babies when they hatch.

It is unexpected, but I think you can manage.
