Yes, but when you start losing work to highly qualified competition then the only answer will be to match them and even surpass their qualifications. It's the only way forward. it's the future of your industry.
Can you honestly say that you're gaining customers due to being "highly qualified".
How many of these customers that you've gained insisted on only taking on the most "highly qualified?"
How many insisted on seeing all you lovely certificates?
And, therefore, I'm assuming, these highly sensitive and choosy customers have already informed you that as soon as a more professional and even more highly qualified outfit knocks on their door then you will be dumped?
