I have started a small DBA in my area to provide services to small businesses here. I have been working on developing it but I am having a hard time selling it without scaring the crap out of the prospective clients. I guess what I am saying is that I have been doing the job for years. Just not getting paid for it and was trying to dig out two things in the OP: 1)What the disconnect between working on your own and getting paid for doing the work was. 2)there was a different area I could/should focus on given my disadvantages(financial, disabled, etc.) Big data and analytics are fascinating to me for example, but only because of the implications and uses of those kinds of skills I can see in a Security related capacity. I wanted to find out if someone would yell, "You need to learn 'X' because it's useful both in some Security roles and you can work doing that as your day job at the same time." Hope that makes sense.
