Polyphemus keeping in NY

[amlepid]

Hello, 
I am just getting into silkmoth keeping and would like to start off with polyphemus, a friend of mine has offered eggs to me.
I still have many questions regarding getting started though that my friend cannot answer. 
I live in New York, and it is nearing the end of fall now. I may be able to get the Polyphemus eggs by the end of the week (9/23). I understand that the eggs may take two weeks to hatch, so (at the very latest) I can expect caterpillars on 3/3. I believe it takes four to six weeks for the caterpillars to go from egg to cocoon, so we can expect cocoons (again, at the very latest) 11/14, hopefully even sooner. Once in cocoons, the pupae will be kept outside to overwinter along with the NY population of polyphemus. I know this schedule seems very unrealistic, but would anyone in the NY area be able to validate this?
I guess in short, my questions are:
Is it realistic to expect cocoons by the time lower NY state leaves turn?
How can I get the caterpillars to grow as quickly as possible?
Will leaving the pupae outside be enough to get them to overwinter?
Thank you

Your polyphemus eggs must be from a source outside of NY.

Depending on where you are in NY, you may have four to six weeks of remaining food source. Once the leaves start to turn they are of little value, and the larvae won't eat them.

I say don't waste your time or kill the larvae. Wait until next year, and get your own local eggs.
