It looks like you might just be starting out, I don't see any listing attached to your profile so I am not 100% sure on what type of listing you will be offering. Also unclear on the amount of time you want to spend managing your own listing.
However this is how I manage my own. I have a cleaning company who does my cleaning $75 for the 3bdrm unit $55 for the 1 bdrm, they claim to specialize in Airbnb cleaning, I can book cleanings online and will do so once i get a booking myself, they allow a 24 hour cancelation or rescheduling without fee which is important as your guests might extend their stay last minute, you and your cleaners have to be flexible. I have keypad check in, initial upfront cost of about $400 for purchase price and installation but well worth it since I don't have to meet anyone to let them in, a cheaper alternative would be a lock box about $40 from home depot.
I just recently purchased the arlo security cameras which allows me to keep an eye on the entrances without driving over. I also have an ecobee thermostat this allows me to change the temperature remotely from anywhere, I love it. I manage my own bookings I answer all questions my guests have and I try to do everything over the app. Once you get into a good rhythm and over the initial hurdles it actually becomes pretty easy where it doesn't take alot of your time.
If you are paying 20% to 40% of your booking plus the cleaning fee you will likely not cover your costs, at least that is for me, so I can't afford a cohost. I do however have 2 cohosts, one is my niece and the other a good friend. When I am out of town I pay my cohosts 10% of the booking for the nights they are covering, I also usually answer questions from my guests while I am out of town. Recently I was in England on a family vacation and right now I have very high maintenance guests, because I knew this I paid my cohost 20% since I know how much a pain in the @$$ these guests are. If you have a # of properties that you will be managing then I would suggest cohosts, however if it is only one or 2 units I would suggest seeing how technology can help you manage and keep the profits for yourself.
