start small by working on projects in your local community, hacker spaces, networking with people who might need your skill. take on anything that is reasonable enough for you to pay the bills.

depends on your level of skill and the school you came out of too. if you're reading news.ycombinator, please don't shortchange yourself and accept $60k, which btw, just happens to be exactly what I did when I got out. my current company offers $100k for friggin QA positions if you know C++/C (i.e. you're actually capable of being a developer). of course, my company is not a startup anymore, so adjust your figures appropriately.
what I've seen is that anything goes for a startup. it depends a lot on how well funded they are and how in tune with the establishment the founder(s) are. but if you ask me, you should really not be assessing a startup based on salary. doing a startup is a passion. why would you do one otherwise? if salary is important to you, then just stick with the small company doling out $100k for a QA position sort of gig.
