Custom 18x18 RPG Board Game

I'm looking for someone to design a dark atmospheric game board for an ongoing project that I am working on. The design for the board must be 18"x18" and contain a 1" squared grid. The game itself is a duel to the death, so the details and art style that are used should be gritty, with a serious tone about them. The setting should be forest-like, with trees, bushes, and maybe dirt roads around the board. The only other requirement I have is there are 5 points of interest, which are described in the attachment (done with Microsoft paint, go easy on me!). Please note that in the attached image, the grid is irrelevant as this draft was done with other board dimensions in mind. It should only be used as reference for the 5 points of interest I mentioned. These points of interest should be within tiles, symmetric to their counter part across the board. I do NOT expect this to be super detailed, or take very much of your time. It's fine with me if you copy and paste layers of generic images into the game board image, and even repeat the same assets throughout. I don't care if all the grass looks the same, and all the trees/bushes look the same, it doesn't matter and that would be fine. I promise I am not going to be picky. This is just for personal use, and I am just looking for something a little better than the foam board I am using at the moment. In the end, I am looking to take the image you provide and just get it printed onto a generic game board for personal use with friends for D&D style gameplay. Thanks!
