While you may be able to find those that fly in cold winter weather, you may find that you will probably not find somebody willing to train you in the colder weather. I know you have a lot of time on a simulator, but that doesn't always mean that you will quickly solo. I doubt anybody is going to want to spent the time it takes to train a student to soloing. And if you do find somebody that is willing to teach you in rush during cold weather I would be willing to guess that you're not going to get very good training. Training a student to fly isn't something that happens in a day. While each student will advance at there own pace, but as an instructor I can tell you that it can take anywhere from a few weeks up to 2 years to learn to fly. It just takes time, and that time is not going to be any fun in cold weather.

I'm not trying to rain on your parade because you do seem very eager to fly (we've all been there), but winter time just isn't the time to learn to fly. Especially since you are in an area that has cold winters.

Hang in there, spring will be here before you know it.
