As a planner or other vendor have you considered partnering up?

I am a planner I primarily do partial planning and month of coordination. I am having a hard time getting my business of the ground and was thinking of partnering or teaming up with someone we would both have our own separate business but we would put some type of package togehter that we could market.  This could even be a designer who does not do planning, photographer or any vendor or venue that does not offer a planner / coordinator.  I thought this might help with my business as well as helping the other parties involved.  Have any of you done this or what do you think of the idea.
