Hi Martin
I have had several trauma clean up jobs and as you say it is not every ones cup of tea it certainly isn't mine as I now turn them down.
Last month I was asked to attend a crime scene of a particularly nasty murder. All murders are nasty you might say but some are just so bloody it's unreal and it's not for me anymore.
This is with out doubt a opening for specialised cleaners,loss adjusters,insurers and the police like to deal direct with such people who are properly trained and with all the necessary PPE.
If you are based in the south east and you do decide to go down this route then contact me I will distribute your name and company to as many contacts that I know including other cleaners who will gladly hand over this type of work.
