This might not be a popular opinion, but I think all the work OP put in here is probably worth more than 50-100 bucks (which is the price of a logo on something like Fiverr). And to make things worse, the logo itself still needs to be cleaned up[1] as it's way too blurry to be seriously used as an app icon, etc.
