It's always going to be easier as a sole trader to specialise in one area, it's a lot of faff and hard work to try to juggle a lot of services and all the time spend messing eat into your profits.
Imagine you do a car valet monday morning then in the afternoon you do a one room carpet half an hour away for 40 quid then dash back across time to do a gutter clear for 40 quid. All the pratting about with all the gear on the van, carpet gear gets blathered from gutter clearing an cleaning cars. One day humping this in and out, an appointment ay 10 o'clock then one at 12 that you are late for. There's all the gear to buy all the gear to maintain, all the advertising and marketting to do for each service.
It could work in a big company where maybe you have seperate divisions etc but as a one man band total farce.
Pick One or two things and concentrate on those.
For me having tried a lot of stuff I prefer window cleaning. The profits are not as good as some of the other stuff but the lifestyle makes up for it. Once you have enough work you know where you are every week, you know whats coming in. when your done for the week your done. If you want a day off you take one. Theres little advertising when full and growth if you want it is easily achieved by simply knocking on doors and more doors. Maybe get a gutter vac and offer that and conny cleaning to existing clients, do a few a month if you want a bit extra or don't do any if you dont.
