Problem here to not underestimate is that if you are not experienced in RFPs you will spend 10x to 20x the time than someone that has experience int these processes, and then there is a real risk that you optimistically misinterpreted some qualification criteria that disqualifies you in the process. So if you have done this before, do it. If have to do it for the first time, you want to consult someone who has walked the path.
