All i will say is that there are people that are built to employ and people that are not , i am the later type , i failed because i jumped in too early , did not weigh up the costs , i just went out and got a second van filled it with nice gear and waited for the money to roll in , it did work to some degree but cashflow was soon a problem , plus i took on some right planks !
Back then there was none of this pension nonsense , the government gave me £500 to start then £500 if my man was still in a job after 6 months , longest 6 months of my life that was , it went some way to covering the layout , i reckon i broke even after about 18 months , but by then i had thrown in the towel , i paid too much , was too nice a boss , not really meant to be a boss !
Hence why i am back on my own , working less and earning more than before , i dont do stress these days
Having said that , you could be the man to do it , just have good cashflow and be prepared for as others have said , a bit of rough before the smooth comes , it will come if its meant to , good luck and dont be a me
