Hi Marcus,
The biggest problem with any campaign to get new business is that it generally requires a follow-up call to jog prospective customers memories .
For most people that is the worst part of marketing/selling. I did post a script sometime ago as I was asked what to say during this follow-up call but cant find the link. Will keep looking though and modify this post when I find it.
The first batch I sent produced two jobs and I have just got a contract with our local authority for a total of £4K for 2006. I have been chasing this particular one since last October when I initially sent them the same letter.
Another 30 went out today which I will follow up in about a fortnight.
Hope that helps,
Sarah
