15+ years ago when budget was on the run, i still remember my mom (yes mom) used to lay tiles on all three bedrooms without prior experience. And heck the outcome was crap haha. cement all over, uneven surfaces, misalignment of tiles, wrong cutting dimensions etc etc... it served a good lesson for us to find someone reliable to do these.

with proper knowledge i think its do-able, but it will take a super long time to finish.
