Here is a letter that you can use to introduce the idea of being your helper to your customers. I found it on the YA Forums a couple of years ago.Feel free to edit as you need to.

Hi I'm _______.

A local Avon Representative. I have just relocated to the city/town/community of __________ and am extending to all my potential clients this great offer:

In order to expand my customer base I like to enlist the help of others, as Helpers.
Helpers are simply customers that help me to spread the word about Avon.

As my helper, your main responsibilities would be to:
1. Distribute brochures to anyone you know that's interested;
2. Collect and submit orders to me by the due date (via phone, e-mail or in person);
3. Collect the payments and distribute the orders.

In return you get X% of the totals in free Avon & mark products.
It doesn't matter whether the order size is $15 or $150, you will always be rewarded for your efforts!
I also like to give extra incentives to my Helpers in addition to earned rewards.

I will always provide you with any brochures, samples, and demo products that you will need and you can give me the orders whichever way is most convenient for you.

If you would like to take part in this, give me a call at home anytime at (xxx)xxx-xxxx or e-mail youremail@addy.com
Also, if you know anyone else who'd like to participate let me know. I can get them started, too!


Sincerely,
________________
Independant Avon Representative
