Op here.
Thank you for all your answers. Im from México btw.
I found this page
www.milvusmap.euI think it is what I was looking for.
You can select any part of the world map. Select standar scales or custom, utm grid, standard papel size or custom.
Also you can change the topo contour. And it will give a pdf map.
I think its a very good page, so I leave it here for you guys can use it too.
And the best part, its free.
