Thank you for your comment. Well, looking at the cost involved, I could possibly going to source it to India, Russia or some eastern european as it's less costly vs if it's USA based. I thought about the project splitting, and the concern I have is exactly the same as your concern in term of code quality. When it's time to merge them together, it would be a pain if one code section is superior than the other and I would end up clean up the inferior one. And my other concern is that who would merge them together as I am not a developer. I could possibly hire a USA based developer to merge them together after splitting them, that's one possibility. But if that developer ends up cleaning up the inferior one, it would cost more at the end.
