Periodically we see topics on freelancing and consulting, and usually a few people comment that they are successful and happy as solo (or self-owned firm) consulting. And often, those people stress that a good percentage of their time is spent networking and marketing to keep business flowing in.
Can anyone in this situation recommend modern, high quality resources where one can learn the networking and marketing skills to use to build a successful solo tech/dev consulting business?
For people like the OP seeking high quality resources with an emphasis on the networking/sales/marketing skills required to succeed as a tech/dev/software consultant, I'd recommend starting with "Getting Starting in Consulting" by Weiss.
Then if you'd like more after finishing that, others to check out are:
* This PDF on sales processes https://www.entrepidpartners.com/how-to-sell-guide
* "An Insider's Guide to Building a Successful Consulting Practice"
* "The Software Engineer's Guide to Freelance Consulting"
But start with the Weiss book first because it gives a good and tactical overview.
