where abouts are you based ?
fill in your profile, i,m sure plenty will be willing to show you the ropes, many on here have tagged along with experienced c/c including myself when I first started.
set up costs, well a little more to it than that .
I was fortunate enough to get a helping hand regarding equipment and advise from an experienced c/c m halliday, who works an area similar to mine,, " hows that for been helpful" enough work for good c/c was is take.
costs well, including training , marketing , equipment depending on your starting machine anywhere from £5,000 to £25,000 I reckon then another vast amount set aside for the weeks you dont work , yes its hard starting !!! especialy the first couple of years.
good luck Geoff
