Do you think I behave like a competitor in the current thread? :-)

No, in this thread you are my best partner. We think in the same way.
I thought about your opinion, that we could be competitors for the project - may be yes, may be no.
1/ you could offer on-site services, we coudn't
2/ for you as a single contractor will be not possible to get IS for more than 1000hr., as my firm with 15 programmers look only for that kind of projects. Even we can make a partnership in some projects

I think that depend on situation they could be partners and competitors simultaneously.
