Make it your mission to gather up a lot of smaller sponsors this year to help build your racing empire.
There are many benefits to this, you can:
1) Fill in the white space on your current car
2) Start a network party on your car
3) Make many connections that will upgrade for year 2
4) Offer you referrals and intros
5) Find it easier to provide sponsors return on their investment
I would much prefer having lots of smaller sponsors instead of putting all your eggs into the basket of a single big sponsor.
Think about it.
