Price, low ball the market and there is a %of the population that will always value price above all else and you will start getting requests. This may sound cold and counterproductive, however now you have people reviewing you and as long as you keep your stats up the Rover alto will keep your name high on the list.
At this point you will be tiered and cranky because you will feel like you have given away your time for 30-60 days but now you have clients and hopefully Rocer’s IT working for you.
Finally Jack up your rates to well above the median rate, and have a plan to keep up with inflation. Your client type will change from those price focused owners to owners who are more discerning. And you will be competing for business with The Walt’s of the wOrld.
My belief is you have to walk into this basically giving away your service to build a reputation and client base. (Side note Rover could do so much more to prevent impoverished newbies) Giving it away I consider where people are charging less than 45/night
(Do the math you are not making min wage)
However once you look like mother Teresa with all of your feedback and you are showing at the top of the list you start trying to get compensated for the level of effort you are actually putting in. ;)
