Sponsorship sales consultant/broker

My entertainment company is seeking an experienced person in obtaining corporate brand sponsorship for our events. We have already put together content for our pitch deck and have a graphic designer. We have a concrete vision of the event concept and sponsorship structure, but we would benefit from the input of someone with experience in attracting corporate sponsors.

We require:
Revision of Content for Presentation Deck
Revision of Deliverables and Benefit Valuation
Sponsor/Partner Identification, Initial Contact & Pitching


Notes:
We prefer a commission structure to be applied with fixed rate.
