Becci just want to give a bit of sage advice, now youve proven to alot of people you can deliver. Your next job is to extract as much money as possible out of these guys. I think you'll have alot more fun if your taking chunks of £300+ of people. 
Nice way to show you see us all as marks to extract as much cash from as possible. We all know that's what canvassers aim for but few are quite so willing to rub our noses in it.
My business is here to assist your businesses grow through obtaining meetings with decision makers in companies you are interested in working with. Telemarketing can be very tedious for people where this isn't their specialism, and for people who are used to be out and about and not tied to a desk!
I have a minimum of 4 hours per session, some customers choose to do this and more on a regular basis, others contact me as and when they feel they need/want to take on additional work. My theory is if I provide good results, these people will be looking to invest further in telemarketing through my business.
Sure having more clients put a larger number of hours through my business regularly makes my life easier, however I am someone who looks at the bigger picture, and no one ever said running a business was easy!
'Skint' clients, as Whizz puts it, are people looking for more work - hence to no longer be 'skint' in the future! I'm not going to outprice my services from them if they are willing to put in the effort at gaining new business.
I have said to Whizz before that we seem to have a very different idea of business and customer service, half the things I have seen him write I disagree with however if this is how he chooses to run his business thats fine if he finds it works for him?
