Hello, I'm looking to get a map made of a earth-like world of my own creation. I've made a few rough sketches but I'm struggling with size scaling and generally making it look exactly how I want it. Due to my job, I don't have a great deal of time to do as much sketching as I'd like. Some basic details are:
•There are seven continents, similar to earth in general placement and shape.
•There are two polar ice caps.
•I'm struggling to make exact scales on the distances between continents. However, the western North American equivalent is roughly 4200 miles from the European equivalent.
•Sea to land ratio is roughly 70/30 respectively.

If there is more information I can provide, I'm more than happy to do so. However, as I am new, I cant receive PMs yet so please contact me at javieruzetaATgmail.com.

Thank you very much to anyone who can help.
