Rob Jackson – Director

"Working with QSL has been a real benefit to us and has provided measurable results. Lee and his team have a great ability to build relationships with C-Level execs from the FTSE 350, which has helped us sustain a more robust pipeline. I would highly recommend QSL to any company  looking for a telemarketing agency as they actually deliver on their promises” - World Television          

Ivar Sagemo – CEO

"As a start-up in the enterprise software space it is challenge to break into the market without any references. Furthermore, our software is for business critical systems and targeted at Fortune 1000. We were challenged with both resources and skills in identifying leads and engaging them in conversations. QSL showed a fantastic ability to work with us to learn our positioning and adapt the messaging to the market and succeeded in scheduling high quality meetings with decision makers." - AIMS Innovation

Rob Hughes – Head of Sales

"I have worked with Lee and his team on a number of projects for over 12-months and can recommend QSL with no hesitation. They exceeded our expectations and were a pleasure to work with on all fronts. Having employed a number of sales companies in the past QSL stand head and shoulders above any firm that I have worked with previously and would happily recommend them." Nelson-Hall
