Sorry about your losses.
This Aussie Farmnote has a temp/time table for making sure you kill the entire life cycle of the wax moth.

I encountered some wax moths in an order of unassembled nucs and frames. Because they were long forgotten stock, I got them cheap. I loaded a cooler with frames and parts in a vertical configuration, put a 5# block of dry ice on top and left them overnight. An indoor/outdoor thermometer with a remote or wired outside probe can be used to track temperatures. That did the job without my wife finding a pile of bee gear in the basement freezer.
I hope this doesn't discourage you from trying again.
To save cash, I'd start as early as you can with a single package or nuc. When they build up and the weather warms, you may want to grab a frame of fresh eggs, a couple of brood with plenty of workers, put them in a single deep and feed. They should raise their own queen and build up for the following winter. Michael Bush has good guidance for queenless splits and I use it to increase my hives.
If you start with a nuc, you may get a harvest in the coming year even with a split, less likely with a package.
Good luck.
