Small Sponsorship Needed

[PolyMatter]

Hello. I create short, fast, educational-type videos.

I am need of new recording software which costs $100. Because I am a growing channel, I am in need of a sponsorship for this money. Are there any resources for small sponsorships like this one where I do not want to partner with a program or anything, just want to do a single sponsorship to buy better software?

Thanks!
