It leaves all the burden of figuring out how I could potentially use your services on me, and I’ll try my best to avoid having to deal with that uncertainty on top of what I’m already trying to achieve.
If you want to be successful offering services be very clear about how you work.
Everyone has a "go-to guy". Often it's a plumber, a handiman, a lawyer, etc. Your might be the "devops guy" or the "Cisco guy", etc.
Build that reputation and then expand.
Also, learn to listen well, ask good questions, and take good notes. Communication when you are independent can make or ruin it for you.
Thank you for sharing this. I feel a lot of client services businesses starting out (read: individuals going into consulting for themselves for the first time) try to build an enigma to make themselves seem experienced and comprehensive. As a buyer, I want to know, up front, what exactly an engagement with you looks like: What will you do? How much will it cost, over what schedule/criteria? What does our feedback loop look like as we progress?
If I get the impression that you're so desperate for work, you'd agree to do anything and everything for money, I'll feel uneasy. If you're confident about being able to do [thing] well, and can explain what it looks like for us to do [thing] together, it will put me more at ease.
