The op is looking at how to get series sponsorship not personal sponsorship...The easiest way to go about it is to hit the trade shows and approach them when they are not busy and introduce yourself and the series to them and explain to them you are searching for different levels of sponsorship for the series..We had Jacket, Series, Associate, Class, and Fasttime sponsorship packages. We also customize them to the companies needs. For example if they only wanted to spend a portion of the amount of said package in cash and the balance in product we would do our best to accomodate them. We never go and push dollars on them. We hand them the agreements (all of them) and ask them to just take a look at them and see what they think. We always make it a point to offer a way to work with them to taylor any deals...We also inform them of what the benifits of marketing with them will be..Ie All social media presence, websites, logos on shirts, banners, track announcements, any promo items they may like promoted, reserved parking, pitpasses, ect. It takes some finess and it can be a little intimidating walking up to someone you don't know and asking them for substantial amounts of money/product. Good luck! Hope this helps some!
