Here's the same logo as above, but the letters completely outlined, also other colors can be incorporated like the ones above. May be harder to have made, but certainly looks more interesting.
12x4 would be a good size or any size within that proportion.

BTW if you need larger sizes and or different file types just contact me I will provide them if they are needed
