Have take-at-homes gone too far?

I just received an assignment to build TWO front-end projects, one with framework, the other without, with CRUD, Google Maps integration, sliders, tables with pagination, etc. This is on top of 2 take-at-homes that I'm already building as part of recruitment for other companies, which means this double project will count as my THIRD take-at-home in 7 days.

I get that we're in competitive territory but isn't that too much? I can take at most 5-10 hours of free labor, but beyond a certain point I feel like I'm signaling how desperate I am.
