Hello,
Sounds interesting...
Well, I do software development during long time, and developed/implemented on both C# and Java (and on other languages as well, C++ etc)
I have not 'some' but good Java experience :) although I'm not using Java during long time already, and all my current development is with C# mainly.
Please, look on my working history page here, there are some actual-life projects (including on Java) I implemented for my clients on this site (and on the RentACoder site). I should notice as well, about I'm very detailed oriented and will provide you with accurate, stable and optimized solution of what you required.
So, I'm interested to know more details about your project and start our collaboration.
The sooner the better, to allow me schedule my working time.
By the way, probably, it would be better if we split the project on several phases, and go 'step by step' to minimize any possible risk for both of us.
Regards
Igor
