Little talk, a lot of writing, up to date portfolios, a few references, a lot of web scraping for opportunities, a lot of tailored e-mails, active participation in industrial forums and local guilds activities, attending fairs and conferences and exhibitions, funnelling interactions into proposals to which you can answer with a written quote and terms of contract. No need to be an extrovert for many of these?
