Also DO NOT CHEAP OUT ON THE FREELANCERS. A good team of freelancers is going to cost MORE then in house developers. The plus side is they are relatively temporary so not a long term financial burden. The projects I see that fail with freelancers are the company gets greedy and pays the bare minimum but as always you get what you pay for. In most cases the work just ends up being thrown away as a CRUD app that does no have your business logic and work flows is actually harmful.
