I want to create a few financial widgets, such as economic events calendar, currency rates/quotes etc. I want it to be fully branded for me, and not have anyone else's logos or credentials on it. I'm ready to pay a fee for using the data, but I want to "own" that widget and be able to do whatever I want with it including reproducing, selling etc.

How do I do that?

I am also interested in having something quite similar being developed. Anyone that could help would be very much appreciated!
