100m hose is the way to go,I do a road where I have 14 jobs having a 100 m hose saves me moving van.
If your short of cash,personally I would borrow some money to fund a decent set up,as trying to do it on the cheap May come back and bite you in the arse
In my opinion start with a good set up, less grief,and allows you to concentrate on developing your business and makes you look professional,and not cheap
