I looked into this and the cheapest I could find wass £900 a month. it would be cheaper to buy one. for a few K and even if it only lasts you 2 years youve still saved yourself a lot.
Or maybe try speaking to a company that hire them out and say that u want to use it say once a week every week for X amount of months thye may cut u a deal
