I slightly disagree with using a '.co'. It's to similar to .com & will result in a lot of typos. If I couldn't afford the .com I would personally reconsider my name. If that's not an option, using a different TLD is fine, especially if it goes well with your name. If you use another TLD, do research the TLD first. I recall the .io TLD having issues a few years ago. Now many people avoid it or use it as a joke when referring to questionable TLDs. Someone else could probably give better info on how to research who stands behind the TLD & how much you should trust betting a good chunk of your business on it. If not, just look up old news stories on the .io drama.
