This idea is about to expire soon. Since no one has provided a solution yet, I'll give it a try.
This is the idea:
Materials (recycled material also):
(1) a square metal plate (from a junked car or something)
(2) inner tube in round shape (since you use this for your product. Your website says it weatherproof and duerable)

Design components:
I. square metal plate
II. a round shape made from the inner tube, size should be smaller than the square metal:
(1) recycle symbol i.e. the green arrows
(2) Blue circle which represents the earth
(3) Your logo "AG"
III.
(1) company name: alchemy goods
(2) Your slogan: Turning useless into useful

Layout:
A. center (i.e. II from Design components)
(1) your logo "AG" inside the green recyle symbol which is inside the blue circle
B. Outer Frame:
(2) you somehow glue (1) above to the metal plate (maybe there are better ways to do than "glue"?)
(3) put your company name on the metal plate above the blue circle
(4) put your slogan on the metal plate below the blue circle
