In my experience, small firms pay more.
I graduated 2.5 years ago, still employed by same company and I can tell you that you shouldn’t even entertain the thought of a salary in the $50,000 range. That is just very unrealistic.
I read a little about your situation in the thread, your skills do not justify that large of a salary. You seem to think you have a lot of experience but really you don’t.
You should be content with anything over $40,000. Anything over $45,000 should feel like a Christmas present. In my experience, colleges tend to fluff up the profession with both job opportunities and salary compensation.
A lot of people have given good advice so far. Just be realistic.
