Hope you don't mind my nosiness, but I checked out the website. Based on that, I have a couple more thoughts:
1. I think you should add all those other services that you list on your website! "Kennel free boarding, their home sitting, grooming", etc I would never have known you do all that based on your card.
2. I hope this doesn't come out bad, and mind you, I am no pet sitting expert and I also don't live in or know about your area, but your prices seem CRAZY cheap!! Are you just starting out? If so, don't feel like you have to be the cheapest in town to attract business, because sometimes if people see prices too low they get concerned and think something must be lacking for the price.
One example is: Only five bucks more for a second in-home visit? I hope they live real close, you could spend that in gas alone to drive back and that doesn't even count your time or care. I just don't want to see you low-ball yourself in hopes of winning customers. I could be wrong, like I said, I don't know your area, but those prices seem insanely low to me. Just some feedback to consider. Very nice website by the way.
PS: I really hope my input isn't out of place, I know you only asked about your cards, I'm just wishing the best for you.
