Hi, I'm an entrepreneur looking for a startup idea.
In my experience, the reason most startups fail is because they never actually solve anyone's problem. So I'm cheating and starting out by identifying a specific person with a specific problem.
So I'm asking you, what's the most annoying part of your life/job? Also, how much would you pay for a solution?
Can you elaborate about which writings you'd personally use this service for, how your ideal solution would work, and what you'd pay for it?
For some types of writing what I need is a proofreading service whose quality I can rely on so that if I use it I will with very high probability not look bad because of my grammatical mistakes. For other writing (such as most emails and comments like this) I could tolerate a much higher chance of the service not catching everything.
For the high-quality work, I could wait a day or so for the results and would be willing to pay, say, $20 per 500 words. For the other work I would want very quick turnaround and would be willing to pay much less say $2 per 500 words.
