Hi
I believe that a call centre of 24 seats can definitely thrive, not just survive. We have seen 10 seater call centres perform to the highest standards here in the UK and make a tidy profit.
Please do ensure that you have clearly considered your target market/s and their own potential for growth as well as your own operation. We have seen so many call centres fail to perform, not because of technology or people..they just targeted the wrong market sector at the wrong time. If you wish to target the UK market for clients take a look at the government export web site at http://www.tradepartners.gov.uk. Best wishes for your success.
Scott
