Honest feedback: those "one day" sites are not impressive, and they will not enable you to win decent contracts. I get what you said, but if you really do have 5+ years experience it confused me why you, someone who want to win clients for freelancing, have not spent any real time, even if a couple weeks, building something impressive for your portfolio. Or building something impressive x 5 given the time frame here.
I have a sweet portfolio site, mostly full of personal projects, that's made it quite easy to land remote gigs. My advice: put your 80-20 focus there.
What kind of thing would you consider impressive? Quite frankly, I have no idea what I should make that would reflect several years of experience (there is also the issue of finding time for all this among other hobbies, but that’s another issue)
There's nothing tricky going on. You should have things that are comparable to what your clients will pay you to build. Mine paid me for their startups, and my portfolio has multiple, complete startup-like prototypes.
