Helium and a little of what you need to know as a balloon professional Part 1

I wonder how many people who read this blog are unsure how much it costs to fill a balloon with helium?

When I first started working with balloons, I had absolutely no idea how to work out the cost of helium, along with a lack of job costing my work, everything that I ever sold was complete guess work, and very bad guesswork at that!I was asked recently if I could help someone to work out how much helium each balloon uses and how to cost it when using the job cost form, so I thought that this would be a useful blog for others too!Before we start talking about costs and prices, lets just take a few moments to review helium and a few points of safety.
