I have a very nice app Idea, which based on my research it is new, and I am quite sure it would be very much valuable. Unfortunately my education is not at all in the computer filed and I have no idea how to make an app. Therefore I am looking for a trustworthy website or person (I don't know) which can help me on making this app. I could also take part in the financial part. And my other question is at which stage I have to patent it? do I have to patent the idea already, or wait until the app is made. Best, Houra
