RC , You have to find what I call your "niche" work!!!!!
For me its misc. metals jobs( stairs,handrails,ladders,etc.) Not small jobs of 2 rails, I'm talkin' stair towers 3,4,5,etc. thats where I make my money!!!!
I've spent THOUSANDS on benders,rollers,notchers,etc. but nobody wants to chase this work!!!!! I have to work all over the east coast but thats what it takes!!!!
Also do same work in aluminum & S.S. Also have a portable unit but mainly use for my own work, WHY ??? Because everybody and their mother has a rig to work and works cheap!!!!! If I get a call for a cutting edge I can blow their doors off by using a wire feeder on the portable, WHY????? Nobody wants to invest in a wire feeder on a portable!!!!!!
Lastly Have your phone kicked from the business to the house after hours, an "emergency job" can go for $85.00/Hr. @ 4/Hr. min.
You just have to find your "niche", Good Luck !!!!!!
