Design a 300x250 Advertisement Banner to go on website

Hi all, I am looking for someone to design an advertisement banner for us. The size of the advertisement is 300x250 pixels. Our company is a nutritional supplement website, and you can see our images and brand at www.UtopiaNutrition.us. The products that we are trying to promote are our Children's omega-3 gummies and Children's Multivitamin gummies. The advertisement that we will need is going to be on the front page of [login to view URL] You will notice that they have a spot for 300x250 ads. ***Most important*** The ad needs to feature both of our Children's products. The focus of the advertisement should be something that goes in line with our current brand, but also cater towards middle-aged to older-aged women. We would like this advertisement to be as eyecatching as possible so that they click into our website, remember our brand image, and most importantly buy our Children's products. This is up to the designer, but we are also offering a 20% discount if the shopper enters a discount code "UN2014" during checkout. This information could possibly be integrated into the advertisement if it would help get clicks and sales, but this is up to the designer. Our main goal is to sell product and build a brand image. If interested, please respond with 1 sentence describing your approach to this project. Thank you!
