I have a web application idea with great potential that I trying to turn into a start up business. I currently work with building application in a .NET environment but for this personal project after some research decided that java will be the best programming language to develop this in.
With this I have some challenges that I find it difficult to overcome and will welcome some feedback on these.
What advice there is for someone in this situation to get an idea developed into a solid web application given the challenges I have? Definitely looking forward in making this idea into a reality. Thanks in advance.
Start building it yourself.
When you come to people with an idea, it's hard to get them excited (and usually justifiably so). If you come to them with a prototype, then that's different. I think it's different for 2 reasons:
No matter what advice you get here, you can't go wrong with just starting building it. It won't be wasted effort.
Start developing language-agnosticism, you seem way too focused on the language in which to implement rather than the implementation itself, if you think you can "make it happen" in Java, not speaking about optimized code, but rather - working architecture which will hold long enough to test your hypothesis, that's all you need.
If you're already a developer, moving from .NET to java is an EASY move, you should try that not for the sake of satartup, but for the sake of personal growth.
Start building, iterate, and improve.
I would actually start this by:
From your list of concerns or limitations above you don't list YOUR TIME has a limitation. If you have a few hours a day then you can build whatever you want yourself. If you know .NET you can pick up Java.
