Create a Video for Smartwatch (paid on success)

Hello. I am on a very limited budget but need a really professional video for a crowdfunding project. I am looking for a professional business partner that will be able to invest their time and expertise in helping me create a video which grabs users attention. I am looking to crowdfund the product and thus need to create a brilliant marketing pitch including video. I am prepared to either provide a percentage of the crowdfunding pitch (if successful) or you can charge a set fee which I will build into the pitch. I will of course sign an agreement through a UK Ltd (registered) company based in London. I have had several friends who are based in this field but their videos were not to the standard I require. There is a product which is inferior to ours on kickstarter which has just broken the $1 million level.
