(we got notice of ANOTHER price increase from our suppliers in early August!) 

Find a reputable contractor who has a bank account in the name of the business(no checks written to their personal name) and preferably credit at Home Depot and local suppliers. 

Your best bet is, to improvise your system internally, like sign up for a pro account in home depot and enable text2confirm or open cash accounts with suppliers or small credit accounta in paint shop.

Not exactly new but doable concept in years gone by I would by building lots I had a builder who had limited cash but credit with his suppliers!

The rehabber walked us (almost 50 people showed up) through the property and then white boarded her whole process, including naming suppliers and vendors she worked with.

I have not contacted any yet but these are the suppliers I am aware of are:http://www.coinmach.com - Probably the biggest and most well known; National coveragehttp://www.aalaundries.com - Not sure they service Ohio; map on web site suggest they do.http://www.greatlakeslaundry.com - Based just outside Dayton.http://www.ccoin.com - Based out of Cincinnatihttp://www.jetzservice.com - Based just outside Columbus and yes I did see the thread about them from a few months ago.Buying and maintaining my own machines is an option but I am reluctant to go in that direction as there is enough on my plate.

I will start net 30 accounts with all my suppliers under a business name.

JBLM is a steady supplier of renters in my neighborhood.
