It seems to me you have got excited and gone too quick too soon partner, first, decide who your ideal customers are and do your research on what they need, what are their pain points and what they are willing to pay for. hint: no one wakes up one day and says I need a software service.... you need to solve a problem, which is to make them money if you can't, try to save them money or time.
in my honest opinion, I think you should consider looking deeper into digital marketing and branding and look for business owners who you can help with advertising and whatnot and offer the software solutions you got as upsells or as optimization for what they already have, this will work wonders. also, a portfolio is a crucial thing to invest in in your early days!
Best of luck!
