yes, fiverr can be a bit "low hanging fruit" though, but i know of people who have made £1million+ over it
tech freelancing in and of itself is still very profitable, i just wouldnt use fiverr
1) find some similar companies who could do with a similar kind of tech solution e.g find clothes companies who have an outdated website
You can pay people/websites to find you hundreds of potential leads
2) do your research prepare a good pitch (powerpoint slide /pitch deck etc)
if you have a hundred relevant leads, 1-5 of them will say yes
