Business cards will not get you much, if anything. I would do a flier (how a lot
of very successful businesses started) on b/w on my computer. Print out
as many as you can and pass them out (not in wealthy areas- they don’t
work for them).
I would literally be on my last $50 in the bank on Monday, go toss out a few
hundred fliers and go into the weekend with $500- MANY times, sadly.
If you need some pointers, message me.
