You could became a sponsor of my videos. There is some ways to do that:
I will insert your logo with my voice phrase like 'Video sponsored by AdventureShop - online place to buy your extreme and travel equipment' at the start and your logo with 'sponsored by' text at the end of the one video
I will insert your logo and some pictures of your service/place/product with my voice description of product you offer (30s time max) at the start of one video
I will insert your logo with my voice phrase like 'Video sponsored by AdventureShop - online place to buy your extreme and travel equipment' at the start and your logo with 'sponsored by' text at the end of the every video during 1 month
You could send me your product and I will test it and record my personal thoughts about it during one of next videos. You couldn't tell me what to say about it, but if you not like my review you could ask to not include it in video
You could send me your product and I will test it and publish separate review video about it. You couldn't tell me what to say about it, but if you not like my review you could ask to not publish it
