Michele Said:

How do I write a little resume/letter if im wanting to get sponsered?

We Answered:

You have to highlight your credentials and relevant working experience in your letter. You have to include a short passage on why or how you think your trip is going to benefit the company, in terms of their public relations. For example, if Canon sponsor an expedition to the south pole with equipments such as the GPS or cameras, their brand name will be shown when pictures are taken. Canon would like that because it shows how durable their eqipments are.

So, you have to tell the companies how your trip will expose their brand to their target market(s), which will benefit them.
