Soundboks for a young artist

Hi, I’m Marco and I started writing and producing my own songs. I don’t only wanna upload my songs on streaming platforms, I rather want to perform my songs on the street. But there is one problem, I don’t have a good music box. After some research I decided that a soundboks 3 would be best for me. It’s loud and sounds good. But it’s pretty expensive and I don’t have that money yet, so if you wanna help a young artist. Thanks in advance.
