Online Ad for Eco-Friendly Product

Help save the environment :-)
Need a small ad (300 pixels wide by 125-150 pixels high) to run on other websites in order to drive traffic to site that

1) sells Climate Kits (collections of tools and tips to help consumers reduce their climate impact.)
2) provides user-friendly information on reducing one's environmental impact

See example ad here:

I am looking for a small ad for websites that promotes my Climate Kits as great green wedding gifts.  (Climate Kits are convenient bundles of items and info to help users save energy, water and money.  Think CFLs, reusable bags, LED nightlight, a tire pressure gauge, etc.) 

Kathy's Climate Kits is a small business that grew out of my passion for trying to get people to start taking action to save energy.  For each kit sold, we plant a tree -- and we also donate $ (based on how much action a user has taken) to an environmental non-profit.

I had a great time designing the product and website, trying to motivate people to positive action.  Now I need to figure out how to drive some traffic to the site.

- Item 1... Should say Kathy's Climate Kits somewhere
- Ad needs to link to http://www.climatekits.com
- Ad needs to promote Climate kits as green wedding gifts
- Image ideas:  a bride hugging a tree; a tree wearing a wedding dress; or a big white wedding bow on a tree
- Tagline options:  Celebrate the happy couple with a green gift     or Give a green wedding gift!
- Would like the ad to be somewhat whimsical, happy-feeling, cartoon/icon-ish

- **Winner will receive cash prize as well as a Standard Climate Kit **
