Other sitters rates are so low it's ridiculous

I haven't been getting any clients, so I decided to look online to see what other sitters have their rates set to. Half the top house sitters in my area are $35 or less per night, one of them is $30 a night,+$5 per extra dog and $5 cat care. I had my rates set at a comfortable $75 per night and $100 for holidays. Wtf is this $30 a night shit???
