Why a limit to sitter requests submitted?

I am trying desperately to find a dog sitter for the holidays, and --not surprisingly-- keep getting "no" answers as so many people will be out of town. Because of this, I am having to ask more and more people, but now http://rover.com is giving me a message that I have asked the max people for today, and cannot submit any more requests for two days! WHY? I am getting very nervous about finding someone. As I hear back with regrets from your sitters, I need to send out more requests, and I cannot wait!

Is there a way to override this limit, so that I can find a sitter?

Thanks so much!!!!
