I guess it's time Uncle 'Nine goes on his semi-annual sponsorship rant.
As someone who's both worked in the industry AND had been sponsored, I will tell you this: do NOT go for sponsorship on your first build. I don't care if you have the next best thing since Murderbox, don't even try. You will come off as a moocher no matter how good your build is. No reputable hardware company will shove hundreds of dollars of gear to you.
You have to prove your worth by building great rigs with your own money first before ever trying for a sponsorship.
Sponsorship is a two way road and its never "for you." You have to have great time, dedication, passion, and a portfolio to even be considered, and even then, it's not guaranteed. You have to provide an advertising avenue for the company(ies) that are sponsoring you, make it worth the cost to them.
If you look at guys like Bill Owen, Charles Harwood, Richard Surroz, Brad Stuart, Rod and Bob of BS Mods, Daniel Harper, and other modders... There's a reason WHY they get sponsors. They've spent thousands, even tens of thousands on their builds over the years. They're reputable, they show improved results over time, and they're ALWAYS looking to do very versatile things.
So until your willing to spend the money, time, and effort, don't bank on getting sponsored. Nobody "deserves" a sponsorship. I oils probably outdrive many race car drivers, but I've never done it myself and would never ask a company to give me a car without showing I'm capable.
Just a friendly 2 cents.
