I've very experienced with sports sponsorship sales. I've worked with NFL, NHL and AAA baseball teams and I also sold sponsorships at the former Sears Point Raceway in Sonoma, California. My clients included Miller, Wrangler, Clorox and more.
I'm a little concerned about the 10 day time period shown on this bid. As I'm sure you know, good sponsors can take some time to cultivate and sign. I do have a lot of relationships in a variety of industries that would be helpful.
Key items I'd need to know: Where are you located - what level of sponsorships are you looking for (local mom/pop, regional business or national ones such as Miller) - what dollar amount you are looking for and what your sponsors could expect for their money. Also, what is the total dollar amount you need to raise and what is your realistic time frame.
I think this would be a fun project. I have a full office and am very well equipped with the latest technology.
