I'm a surveyor and a GIS Expert with years of experience in the office of the surveyor-General, I've read your project description and I've seen the Topo map example in png, I say to you that I can fix your project, firstly, I'll be using Google Earth to obtain the datas of the location specified, then I'll useTCX converter to convert the datas in kml into CSV. after I'll launch QGIS/ArcGISand add the the resulting data to obtain points on QGIS/ArcGIS canvas then create shape file for the resulting datas thereafter use the contour tool and TIN tool to make a Topo map which I can now do some changes to fit what you want then save it in Jpeg/png/PDF format, therefore send it to you.
I can also make use of Surfer software to make topo maps. Either way chat me up if you'd like me to execute your project, mind you Its what I can execute in a day.
