How can i get sponsored for fishing?

Me and my friend run a new, growing saltwater fishing show on YouTube. Here is the link -http://www.youtube.com/user/WestFLFishing?feature=mhee and we are looking for sponsors. We kind of have one, a small lure company is giving us free stuff if we use there products in our videos. So i sent out a few emails to some tackle companys and boat companys to see if they will do some kind of sponsor deal. Do you think they will be interested? Any other ways i can try and get sponsors? Thanks
