Hi Warwick
My advice is don't sell.
Think about it this way. Its hard work being a carer (BTW Well Done) you will need time off so having a way that you can earn money to pay someone has its advantages. Work out what it will cost you to pay someone and it my view you can earn much more per hour. Then take days off as you need them. best of both worlds.
You would need to take time off for each carpet clean and then your day off, Would you not get a few hours each day that you could clean when work comes in? Plus you can earn money to take mum out for the day. If that is posable? Not saying do everything that comes your way just cherry pick best jobs
Good luck whatever you decide.
Respects
Ian
