Hello @JohnnyZenith and a warm welcome to the Community Forum 
You are most definitely in the right place for answers 
I have attached a couple of links you should find helpful regarding membership types and the money back guarantee
As you are just starting out I would recommend adding some references to your profile, you should find the attached thread helpful
I have also attached a video for you to explain how everything works
Also, remember you can use the spyglass symbol at the top of the page next to the TrustedHousesitters logo and search for any questions that you may have as they have most likely already been answered on here and of course if not then please just ask!
