If you brass neck it, you might be lucky, on the other hand, you might deliver a very poor quality of service. In which case, you would not deserve to get paid and that's being polite.
I get fed up with the chancer and con merchant attitude which is apparent in some postings. As has been said many times, by many people " Talk's cheap................show me the quality "
It's also often quoted that you can't raise prices, if you start low!
This is totally and utterly nonesensical crap. I increased my charges every year and my clients expected it to cost a little more each year.
If you increase by 5% per annum you will retain your clients and build a client base, which, if handled properly, will save massively, on marketing costs. I sugget you do the maths, by adding 5% to your current charge for a living room, then taking that total and doing the same again and again.
Nothing is more divisive than, what to charge and I have encouraged people to increase their charges, but by 5-10 percent and annually thereafter.
The people who say you should start high, are IMO encouraging "coyboyism" and giving the industry a bad name through their inexperience, which results in, low quality of work, but with high charges.
Exactly what's highlighted on TV'S rogue trader, type programmes.
Incidentally..............just havng the confidence and equipment does'nt make you a pro in any walk of life and to operate that way, is taking a huge risk with other peoples property.
