Sponsorship Package - for new web series

I am looking for someone to develop a sponsorship package for a new web series we are launching. The project will start filming in August/September this year and move forward from there with episodes every 2 weeks.
We are looking to raise £75,000 through sponsorship and need someone to develop a package to be sent to sponsors, they should have experience in this area and good track record raising money from sponsorship.

In Summary the show follows two motorcycle rider as the start their journey into racing. Starting from their first track days, through getting a racing licence, and then racing the rookie 600 race series.

We are hoping to use the MV Augusta F3 motorbike for the show http://www.mvagusta.co.uk/f3675.php.

The sponsorship will be a collection of cash support and in kind sponsorship, and as a sponsor companies can secure logos on the bike, clothing and helmets along with a host of other options in the show. I will be looking to work with you to develop what we should offer sponsors and how to create the package.

Pleas factor in time for going backward and forwards with ideas until we reach the final package.

I have no idea on price which is why I have left it blank, so please quote what you think is reasonable.
