Congrats, this is a good idea and well designed.
I think users need a taste of the product before they're going to part with $199. For my example search, I have:
- 17 high risk domains
- 7 medium risk domains
- 16 low risk domains
To show the power of the product, why not show one domain from each category?
I think calling it "TypoDomains" might be selling yourself short, I would name it something that indicates brand protection.
