Is there a 3 PHASE inverter out there that can manage a possible output of up to 60.000 watts for a tanning shop?

I know we can change the power supply via energy company but this is been quoted as a 6 week minimum wait and would rather get set up quicker than this. Electrical needs as follows which has been copied and pasted from a sunbed website: Power requirements: Most people underestimate this, even some electricians if they haven’t installed a sunbed previously. As a rough guide, a 200 Watt lamp uses about 1 Amp of electrical current, so a 40 tube 200 watt sunbed uses around 40 Amps, which equates to 9.6 Kilowatts. This means that the cable supplying power from your fuseboard to your sunbed room needs to be 10mm (size in cross sectional area) which is thicker than most shower or cooker cables. Its amazing how many people think that the sunbed can be simply plugged in to a conventional socket! A 13 Amp plug has a maximum power capability of 3 Kilowatts before the fuse will blow. What’s more, a sunbed is what’s called an inductive load. This means that when it starts up, it draws around 10 – 20% more current during the first few seconds, just like an electric motor. Many electricians do not realise this, and although it does not affect the cable size required, it does affect the size of the circuit breaker (fuse) in your fusebox. If the 40 tube (40 Amp) sunbed in the example above was supplied via a 45 Amp circuit breaker, it would trip out on start up, giving the impression that the sunbed was faulty. There are two solutions: one is the obvious, to fit the next size up circuit breaker. Unfortunately, this is either 50 Amps, or 63 Amps. The wiring regulation do not recommend a 63 Amp breaker to protect a 10mm cable, as it results in a mismatch that can be potentially a fire hazard, so a 16mm cable would be required, which is much more expensive, and cumbersome to route through your shop due to its larger physical size. The other option is to use a Type “C” circuit breaker in the fuseboard. Electricians call these ‘motor start breakers’ and these allow a higher initial start-up current to flow without tripping, as used on industrial electric motors. Problem solved! Leisure Centres and hotel chains may also insist on having what is known as an RCD, or Residual Current Device fitted, also called RCB. This is similar to a circuit breaker and provides additional electric shock protection to the sunbed user. Whilst this is not yet mandatory in the Wiring Regulations, larger companies (and most suppliers of new commercial sunbeds) tend to insist on installing them to reduce the potential of electrocution. In our current litigation-crazy society, this is likely to become more common in the future, and so fittng a RCDis recommended
