Example: Market size 150,000 or less on a yearly subscription model ($60 per year) for a total of $9 million annual revenue at most. Costs estimated to be less than 500,000 annually.
Wow, sounds like you have an amazing profit margin. The key is GROWTH. Continuous and stable, with the ability to predict future growth.
Therefore, your market niche is very important, to feed the growth curve within an order of magnitude and can't be too vague.
As others have mentioned, investors look for a $100-200 million valuation potential, as well as the ability to morph or expand as needed.

Having raised over $100 million in angel and VC funding for startups I've founded and a couple others I've advised, I have some related experience in addressing this question.
The company you outlined above seems more like an angel or friends and family deal for a lifestyle business than a VC financing round for a technology startup.
VC's want to see a billion dollar market opportunity potential, and a company that has a chance of reaching at least $100 million in revenue by year 5.
I'd be happy to talk further with you about fundraising options if you'd like to give me a call sometime.
Likely best you look through docs on various VC Websites (there are many).
If you have a flow of investment (say for example in traffic) + a flow of sales, so there's a consistent ROI over some period of months, you'll attract far more capitol + have to give away less of your company.
Most VCs I know will be way more interested in consistent, proven ROI (even if total revenue is small), than estimates on paper.
