Purchasing A Banner [OSGP]

Willing to give the OSGP as soon as the finished product with watermark is sent to me and we agree on the outcome. I will give the OSGP for the non-watermarked version. Will go first for it this way.

All I'm looking for is the following:

Size: 400 pixels wide and at least 150 pixels tall.
Incorporated Image:

What I'm looking for:
Just want that picture incorporated with a decent background for a banner. Will pay 5M OSGP for it (negotiable?). As stated above I will also go first one the preferred watermark version is created. This picture is based off of the Metal Gear Solid video-game series so anything really from this series will be appropriate.

Some MGS Resources:
Big Boss Images

Solid Snake Images

Metal Gear Solid Images

Posting those because from what I seen not a lot of people are familiar with the series (very sad).
