What pump or compressor for tubeless (difficult to seat tyres)

cant get my tyres to seat onto the rim using a standard track pump (worked fine for other rim/tyre combos, but not current set up). Took it into bike shop at BPW and they couldn't seat it with their compressor - they said it was limited to a fairly low PSI due to h&s. They recommended using a compressor that could achieve higher pressure. Sp[ent the day using an inner tube praying that i wouldn't get a flat!

So, decided to get myself either a compressor, or one of those track pumps or tanks that build up a body or air under v high pressure, enough to seat the tyre. Can anyone recommend either the pump / tank, or a cheap compressor. Thanks.
