Of course sometimes you have to do the hard work, but now that you are hiring instead of trying to find a person that master 3 fields, look for someone that master two of them, maybe the two where you feel less comfortable, a designer can easily fit front-end or a back-end dev is able to work on front, that may help to find someone capable to start working and later they would learn the next set of skills you need to be considered a unicorn, hackers love to learn.
