I need a tank

I was thrown into the world of balloons. Due to the closing of a major supplier in my local area I've decided to try to capitalize on this opportunity. Do you know any good sources for helium tank rentals. I'm home based so I need something small, not sure where to start but I've already been through 3 of the cheap throw out tanks, so I figured I need to have some sort of helium service.

I have heard that companies that rent building tools usually have helium tanks. Might want to see if there are any in your area.

We get our tanks from a gas surplus store. They sell all kinds of tanked gas
