In these times of full grown software claiming to be “free” because the “sourcerers” (companies, of course) know the sneaking way to steal their earnings from everybody via (e.g.) the advertising costs included with everything prices, I wouldn’t assume many are ready to pay anything for serious small (casual) software development.
If you (@DaviCaldas ) know a profession well enough to be able to develop a valuable specialized software solution for those practicing it, you should also know a sample of these people you can ask, to find out what price they might be ready to pay. Whatever the price: No sales, no earnings. Simple?.
(The question may be OT, but its meta aspects are of interest here. Opensource communities live in the real world. There is only one currently.)
