Design a Banner for Web

We are an online retailer that distributes items for air purification looking to have a banner created to use as the header of our page. We have included our logo which we would like included along with an image that we are looking to use or another image similar to this that would con-notate nature, breathing, earthly, pure & calm. Looking for a a unique design- please use your own creativity to present 3 different versions that would tie these items together that would have a simple, eloquent and tasteful appeal to our consumers. (Again looking for creativity outside the box- what would appeal to you as a consumer to tie it all together) If the attached image of the boy and dog are used this will need to be edited (take note of attached example where arrow points) enjoy the picture/coloring/nature image but do not like the dark green/trees in between the boy and dog in the background. (we would prefer this image be used in a least one version as a choice) Will require multiple revisions and would like our final image selection to be delivered where one has the logo and one without the logo. Final deliverable to include: image in high res- photoshop we use windows 7 psd- need at 72dpi (1 logo-1 non-logo) jpeg 1770 x 721 pixels(1 logo-1 non logo) jpeg 122 x 270 pixels (1 logo- 1 non logo)
