Hi Elaine. Something else to consider, who are you sending this packet to? Is it going out randomly to businesses that may or may not be interested in your services? Or is it going out to businesses that have already expressed an interest? If you are sending it out to random recipients, I say keep it short and sweet. You don't want to waste your marketing materials on businesses that may not have any interest what so ever. Additionally, if your materials do fall into the hands of someone who is interested, you will have included just enough information to encourage them to either call you or visit your web site. If you are sending your packet to potential clients whom you know have already expressed an interest in your services, then it is definitely wise to send a more in dept packet. Just my 2 pennies but I hope it helps!
