There is no brief for this project, so there can be no proper quotation for it. You are lumping social photography (weddings), in with business-to-business work, all of which need individual briefs in order to provide even a ballpark figure. What is more, most social photographers do not cross over into b-to-b/commercial - they are very different skillsets, using different equipment. Try again with a proper brief and you might get professional photographers pitching for it.
