The price rises will help.
With the work, have you considered moving customers from month / six weekly to 12 weekly, and charging 50% more for 12 weekly work?
If you do this, you will get a much higher profit margin, but without doing that much more work - although obviously, it is a bit more work cleaning houses on 12 weekly as compared to 6 weekly.
The other thing that may make work less of a hassle is moving customers to DD if you wish and getting rid of any 'hassle jobs' and bad payers.
60k is a brutal schedule for anyone to do AND do all the things that runnning a small business requires you to do at the same time. To hit that you will have to consistently be doing around £300, day in day out, Monday to Friday with just a month off a year for bank holidays / illness/holiday.
And it will grind you down eventually unless you have someone in the background doing behind the scenes stuff for you.
You have a dream of getting an employee and earn a living from your workshop. Visualise that goal and do something every day to move towards it.
It is possible to find decent employees, it just takes time and you may have to go through 4/5 before you find your man/woman!. If you commit to it, it WILL happen. Ask yourself: How much do you want to earn a living from your workshop?
Other stuff that may help: Intermittent fasting where you fast for 16 hours a day for a few days a week or more, avoiding processed food/sugar/caffeine/booze most of the time, and listening to Greg Plit motivational videos on youtube!
