I was in your shoes not even a month ago. Get that bator setup now, double check the turner that it does work. The thermostat is very touchy, and you will have to "tinker" with it so you get that temp. set where you want it...Everyone says 101 degrees but you will be fine at 99 or 100...better to be under than having that temp up to 104.
The temp will raise and fall on you so be sure to check in on it a few times a day. I put filled some metal lids in the bottom of the tray to help with having some extra water in there, ( i had to add water 3 times during the incubation), it helped get my humidity up to about 60% then come the last 3 days I took out the turner added a wet sponge to get that humidity up to 75% and let the chicks do the rest.
Im sure there will be a few folks say I did it all wrong but this worked for me, I had a hatch out of 6 chicks with 10 eggs.
