Are you on the same page when it comes to finding ways to bring in revenue?

Don't act as if you're a manager. You're more like a product development organizer and status updater.

I have trouble finding a CRUD job to work in. At least the expectations from employers are not that high.

Others have made excellent comments here. I want to add this:

- Mention that unless it's for a certain price range, you're no longer in the market. However, you will keep them in touch when you're changing the policy again.

- If the pricing/arrangement doesn't work for both parties, say you're happy to refer them to someone else who could use those projects.

Also, stay in touch with them regularly, but you don't need to go overboard on this, as you want to focus on your company.

Have you tried testing your idea without coding or hiring people? Most ideas in start-up founders' heads usually aren't any good in terms of making money. It's not until the pivots when they found profitable models.
