Honestly, although IM can bring you some decent money over time, it normally isn't something that you can start on a dime and instantly make bank. Contrary to what you are saying, yes, you can get job offers - even in December. How do I know this? I just retired from the Navy and have been applying for jobs. I've had phone interviews this week for 2 different decently paying jobs ($60k+ - one of them most likely $75-80k)... and from the indications I've had from them, I should get at least one offer, if not two. (The higher paying one was talking about us talking compensation even before I have the technical interview)...
So, simply put... don't be afraid to get your butt out there and look for a JOB... that's the fastest way to make income... and more reliable. THEN work on IMing... that's my strategy - I'm hoping to make decent coin using some of these methods, but in the meantime, I have to feed the family, ya know? lol
Good luck - I hope you find a way - soon,
