Hi Sam,
Well to be honest the NSS's have not made much difference to me in a negative way.......
I seem to be getting more clients from them lol....................
A lot of clients come to me after they have been there and have been disappointed with their services from them.....chatted to their collegues and then have been referred to me by them.......
So if anything they have boosted my business ...............
My existing clients trust me 100% and will educate their friends who use NSS..........
Upholding my standards and not trying to compete pricewise has payed off for me......... but I knew it would lol...........the more NSS appeared around me,the more education I got, if you can't beat them give them a good run for their money lol...........
HTH
