That was the biggest advantage of Google Hire: it was actually affordable as a startup.
This is the main reason I built Agave Hire (agave.com). I wanted something I could easily customize, and also wasn't expensive.
Check out https://hirehive.com, I'm the CTO and we have a great set of features. Our pricing is based on the number of open roles and prices start at $49 per month for 3 open roles.
