I have been looking for clients for quite some time. I'm an IT freelancer. Besides the usual Google search and freelance web sites I ask to know about other sources.
After reading initial answers which included suggestions of web sites I thought to delete the question. Perhaps my writing 'Besides' in the question didn't help. Since I wrote the original question I have not found answers. I looked at other similar questions but again saw upwork and freelancer and usual advice. Since my original writing I have become convinced that freelancing in IT is not feasible and would advise people to research as much as possible before depending on it.
