I will think about it for a bit; I'd love to help.
One piece of advice, I know adding the dash and remove the "s" are meant to differentiate you from the existing businesses, but those small tweaks might not be enough to set you apart from the others. If customers or potential customers forget the dash or accidentially add the "s", the competition will not only come up, they may actually gain the business intended for you. I would think about doing something completely different. If there are already 2 businesses out there with a similiar name, I'd look to do something fresh to stand out. Just my $.02
