Hi Julie,
Huge congratulations, what a motivation you are!! Regardless of challenges I love the idea of being a soloist and having full control over our own destiny!!
I absolutely understand your difficulty with choosing a business name, my business path started as a spur of the moment suggestion by my husband who is always behind me assuring me I "have what it takes"
BUT---- Talk about alot of brain wasting hours trying to figure out a business name that wasn't already registered and had an available domain name!! I really started hating domain squatters over the last month I can tell you LOL!!!
My suggestion is to write down the keywords that you think suit your business, then play around with a combination of those. Once you have that, you should try searching for available domain names, and then even for "keywords" that people use to search for your type of business online.
It will probably take a while, but it's very fulfilling and exciting when you strike gold with the right name....
i know that doesn't solve your problem, but I hope it helps some
