Unless you are planning to open a chain of nail salons, keep it simple as the name doesn't matter too much. Jodies Nail Salon has a personal element and allows you to explain why you are passionate about nails and will provide a unique service. It is much more important how well you provide the service, how you stand out from the local competition and if you do that right, the customers will remember your name.
At the end, you need to create a reputation. There are no short term fixes to this. It takes some years of effort and continuous education to deliver an exceptional service. All businesses have to do this not only nails. And it is not easy. But with dedication it is possible. Good luck!
