I haven't "lost a lot"..so not much experience in pulling out of clients. I'd be concerned about having my remote tools there, so as soon as I was notified..I'd send an email to the "new IT guy"...CC'ing the soon to be ex client...to transition services. This way the client is not exposed. (like..removing A/V). I'd still want to pull my remote tools. And then line up any/all other tools, backup, email filtering, email itself, DNS control panel, domain registrar, etc etc.
Re: BNI...we owe a huge part of our success to BNI...my colleague has been in it for over 15 years, and for over 10 years I was in a different chapter, culminating in my final year I was chapter president. The chapter I was in, started out around 18 members..when I left were were hovering 30. There's a large chapter close to me that averages about 75..biggest in our state. Their long time IT guy stopped his "consulting job" and took a job heading up the VoIP installs for an ISP in the area. You can bet we cozied up good with him..got a TON of his clients. I'm still making money from MSP clients I've picked up via BNI, I easily pulling in way more per year than BNI cost....multiplies more. Getting your annual investment of ~$1k back each year should be cake walk, should be getting 5 digits of sales via BNI.
A lot of people make the mistake of assuming all BNI groups are the same and just join the first one they find. Or they've been to 1....and think that's it. Chapters are made up of people. People vary. Some chapters are..not as good of a fit, others are better, others are great. You also need to seek out chapters which have really strong people in the specifically good types of business (sphere of influence) that can help you the most.
Can't be the quiet type to sit in the back and be an uninvolved bore. It's not for the "socially challenged" types (which..a lot of stereotypical IT people are). Success in BNI involves being an active member, getting involved with other members, getting up there and giving those 30 second commercial with personality, and giving really entertaining/engaging 10 minute presentations. And doing things with other members outside of BNI, getting to know them, getting involved in community events with them. Every group has members who you learn will give great 10 minutes presentations and you look forward to those and those members who are boring and giving 10 minute presentations where everyone is yawning and nodding off. Which do you want to be?
I headed up several community events when I was BNI prez, one was a huge fund raiser for a local services shelter, raised a lot of money, got the event in the paper..including a picture. Lots of successful business people get involved in various local business organization such as BNI and local business Chamber groups. And remain involved with them throughout their career. I know plenty of very successful biz owners that still go to them all...does't mean desperate or starving...it means they enjoy being involved with other biz owners and with the community. For some it's a way to have a scheduled "outside of work" social hour that normally you'd not carve out for yourself. Nice to have a break once a week where you don't dive into work at 0530...
