If the pay is not high enough for your needs, you shouldn't bother looking at startups, or at least you shouldn't be looking at pre-series-A startups. Everybody has their own motivations for why they choose to work somewhere, and money/compensation isn't always the top consideration. At early-stage startups where money is tight, salary will usually be difficult to negotiate too much, but equity can be negotiated more easily.
The equity is preposterously low for an early stage startup. Even if the company were incredibly successful and ended up being worth $100 million (unlikely) and your equity wasn't diluted at all (unlikely), your equity would only be worth $50k.
