Cost-effective software dev company

I have a pretty small startup, and I want to develop a good app for that. Do you think it's possible to do without spending a fortune?

Man, I think it's impossible because you need to pay a lot if you're willing to have a decent product.

Actually, it's possible to find an affordable company to work with, even though it can be pretty hard. But I managed to do that because I had a really small startup myself, and a custom .net development company helped me come up with a great product that improved the performance of my business a lot.
