Seeking advice for IT Business

In the region of South Africa where I reside, finding employment opportunities is a challenging task, particularly for individuals with my specific skill set. I am eager to establish my own small business within the IT industry, where I excel and can work for myself. However, breaking into this industry is daunting due to the prevalence of scammers and fraudulent activities. It is crucial to remain vigilant in today's landscape. I am curious to know, what factors would instill trust in you when considering such a service? Aside from the numerous testimonials I possess, would active participation in a computer-help subreddit and a positive karma score be beneficial in gaining your trust?
