Hi there,

I would give it a try, if you will accept absolutely non-professional work (this does not means "ugly", just not.. "WOW" as a lot of maps posted on this forum. There are really incredible artists here.) and loosen your deadline a bit.
I also have another suggestion... since your description is fairly vague, you could maybe post a rough sketch of what you want (main land features, some other names...) and I will post my translation of it into a map :-)
