How Do We Testify?

I was wondering if any of you lovely ladies would have any ideas on how to testify to people who are well off financially? I know they are people, just like anyone else, but...I don't know, it seems a little harder. At first we(our family) thought about just putting tracts on the doors or in mailboxes, etc. but we found out this is a nonsoliciting zone. It is against the law to do that. We know our lives are living testimonies. And I know that that alone makes a huge difference. I think since we have four children, especially here, where everyone has 2.5 kids, people tend to "look" at us more. lol Either that or we're really funny looking. lol ;0) Anyway, they see us doing things as a family, and people come up to us and say hello, make comments etc. I pray that they see Jesus in us. However, we would like to do a little more. We want them to "know" Jesus. I'm not saying that none of them don't already know Him. I feel like south Florida is VERY vain. The women are into themselves, and the men are into their cars and all the little toys that they can collect, boats, etc. I hope I don't sound like I am being judgemental, I'm just trying to paint a picture, so that you know what we are up against. When my beloved and Kayla went to Peru on the missionary trip (two different links), the areas that they visited were VERY poor. They visited people that had nothing except a bed in a little room. The entire little community shared one bathroom. (I tried posting pictures of this, but blogger wouldn't let me) I will try again later.) It was very easy to tell them, "Jesus loves you. Do you want Bible studies, etc." Everyone was very accepting of the message my beloved and the group were sharing. How do we do that here? Any ideas? We feel the burden of witnessing, but are at a loss as to how to go about it.
