I'm trying to re-install High Sierre to get a bit of software to work and now all i get is my macbook trying to boot, then a swooshing noise, then back to trying to boot, over and over and over again.

That sound is what I've heard when force powering off the T2 Macs (2018-2020).
If this laptop is a 2018-2020 Intel Mac with T2 security chip and you are having trouble reinstalling macOS, then you may need to perform a DFU firmware Revive (or if you are erasing the system, do a DFU firmware Restore although the Restore will require you to use Internet Recovery Mode to reinstall macOS since USB booting will be disabled again).

If this is indeed a 2018-2020 Intel Mac, then I do not recommend having it repaired for multiple reasons....the money would be better put towards a new laptop.
Mac not booting and making a swooshing noise on repeat
