per rug? 6x4? 12x9?
To do rugs properly they need to be taken off site. Off site cleaning commands higher pricing as it's seen more as a speciality with a higher perceived value, rather than "just run over this while you're here"
The problem for most of us is that we're one man bands, myself included, so unless you've got a nice big workshop or garage at home to use you can't bring rugs away. You need a unit, which is obviously a huge financial commitment, which means you need to start marketing the service heavily... which means turning over higher volumes, which means staff, which means.... sod that I'll stay a one man band and just run over a rug in home if they ask
This is going to be my next leap, but also using the workshop space for leather work. Gonna take a bit of planning and a stiff drink before signing on the dotted line!!
