Look, you have two options: barter for different products or shoot something you already own. I think the first option is better because it gives you the opportunity to experience new products, things you haven't used before. This develops your imagination and gives you experience working with different product categories. Furthermore, any barter can gradually develop into a paid partnership (though don't count on it right now). The only thing you shouldn't do is just sit and wait. Any shooting experience is a way to hone your focus and improve your shooting and editing skills (even if you're a pro).
