Well, for outfitting your first kitchen on a very limited budget ... I would visit garage/yard/estate sales. You can probably find everything you need for basic cooking (1-2 skillets, 1-2 saucepans, a 5-6 qt soup/stock pot), a couple of microwave safe Pyrex bowls, some baking sheets/pans, and dining (plates, bowls, cups, glasses, flatware) for 4 for under $50. I would stear clear of non-stick cookware unless it's from an estate sale - unless it appears to be scratch free. Garage/yard sales are generally only prevalent in the summer - estate sales can happen any time of the year.
You can find the same things in thrift stores like Goodwill or Salvation Army - but they will cost more.
Don't worry if things don't match - that is a design style called eclectic,defined as:A personalized decorative style that combines elements from multiple periods, sources, textures, origins, and styles. Sometimes called "mix and match."
And, you can pick up some things you might need at a 99-Cent/$1 store.
No - this isn't the "ideal" kitchen - but it will get you started. Then, as your finances improve - you can always begin to replace things with better quality stuff.
