I have written a simple but powerful text application which can be plugged in into many existing projects. I think many people (individuals, start-ups and big businesses) would like to have it, but I'm not sure how many would be prepared to pay and how much.
Right now I am building a web service to demonstrate it and thinking of what's best to do next.
Here are some thoughts on my goals to put the problem in context: I have a PhD in Computer Science, specialized in knowledge that is in high demand right now. I want to share my skills with others in form of consulting jobs. In a year or so I would like to organize a start-up which would produce similar text apps.
Would you recommend to release the app for free to promote my brand? Or release it for free as a trial, with charging after 1 month of use? Or free for individuals and at a fee for businesses? What's the best way to judge how much is appropriate to charge?
Thanks a lot,
