Do you think it's best to specialise in one service / sector or offer a range of services?
Being a specialist can bring in clients looking for just that - an expert in the field, (no pun intended!). It also makes the choice of vehicle, tools, equipment and even employees that much easier. Your website can be heavily focused on that one sector, (a bit like Arbtalk really), and can reap benefits from that. Keeping up with training and H&S requirements might be easier as well. You might be able to command a premium rate for your service or through specialist equipment and staff, simply be able to make much more profit on a standard rate.
Having said that, what's the downside? If demand for your specialist services rises and falls, so does your income. If your service is particularly affected by the weather you might find yourself sat at home with no wage coming in.
You / your business could offer a range of services. This can help spread the net wide and bring in a variety of revenue streams. Diversification allows you to offer more services to your customer base and often clients seek out companies / individuals who offer a one-stop-shop, keeping the whole process easier for them.
Diversifying can help keep the work interesting. Perhaps you'd get bored doing effectively the same task week in week out?
Diversification also brings its own headaches however. Firstly you're perhaps no longer viewed as a true specialist. You're vehicles, tools, equipment and employees all have to be geared to a range of services with the danger that you're not really optomised for any specific task. Vehicles are a good example of this; a specialist might buy and equip a vehicle ideally suited to their trade. A business carrying out a range of services often wish for a pickup one day, flatbed the next and a panel van the day after!
Targeting a website or adverts to a range of services has its challenges, (as we all know!). You're often trying to be all things to all people, which has the danger of making you look a bit unprofessional, (or unbelievable).
So what's your take on it?
Is there any real one size fits all answer to this and what are your experiences of being a specialist in one sector OR someone that offers a range of services?
