I think you mean low fidelity, not low resolution. Resolution is video, fidelity is audio (by convention at least).
And the only advice I'd say is that don't aim for anything. You will in all likelihood not go anywhere. You won't make money from it. You won't change the music world. Do what you like. If you get an opportunity to play in front of an audience, or have enough people interested in a recording go for it, but don't rely on having to do anything. For example, don't make any big equipment purchases thinking you'll make it back.
If you want to make money, be a cover band or something like someone said. If you want to make some big artistic vision or something, that's fine too, just do it. If you're lucky someone will be interested and go for it. But trying to balance them, trying to express your musical ideas and still make money and be something big you're as good as dooming a band that could have been a great way to support yourself, or express yourself.
