I recently went it alone, and now I’m trying to start my own business InHouseIT.ie ,providing(linux) IT support. I finished up in Blacknight in July after a year and a bit working there.
From my conversations on the phone to different (blacknight) clients I figured out that there is a market of this Linux stuff 
So 2 months on and its really going slow, Who knew it would be this hard to start a business
I think my problem is that I’m not a business head and so I’m learning the hard way about starting a business.
To be continued….
