Well there is several ways to learn and a good one of that is indeed to look at what others have done and consider how you can do so yourself. You can of course always request a map, which I if I were you would have changed the title to and
posted here instead, but enough about that.
What I would recommend for you as a learning experience is to find a list of maps you like (you have already made a mention of several). Find out what you like about them, do they have an awesome model you simply can't live without? Do they have a great way of combining spells whatever. Then you move on to search here on the forum for those things, maybe the model is located in the
model section on hive, maybe the
icon(s) you want is here as well. Same goes for those
spells that make a map nice in appearance and add that extra bit of fun.
Then you would have the initial "extra stuff" for your map (and it will actually be your map). The editor as you will soon discover is not a tough tool to use - in fact its remarkably simple to use - as long as what you want to do is kept on the basic level. Placing grass where you want it and so forth and for all of that there is a lot of tutorials which are made specifically to people new to the whole ordeal:
Beginners Guide or
about terrain or even
how to create a melee map all of which goes to the basic of things, allowing you to get your hands on the editor and do exactly what you want to do without being limited to others imagination or trying to explain what you want to people who don't understand it.
You can find even more of those
tutorials in its section on Hive.
In regards to creating a special map for you, I doubt you'll find any takers - unless they already wanted to make one - but alas there is still hope, since given the extreme amount of maps made for Wc3 it is indeed likely that something similar to what you want is already out there. In that case try to find it, post some specifics about it and start to consider what you want to change for it to be perfect. If its just some minor adjustment it is very likely that someone will help you out with it (This someone could for instance be me
).
But even if map creation by itself is a fairly "simple" task, what matters is that it do take a lot of time to do.
Hence the reluctance to make one for someone where even I have trouble understanding what your actually asking for (in terms of the map) (If you have the triggers and models - you basically need someone to do the terrain and the object editor stuff - which btw can be quite the time consumer). But it is also the most simple thing of all to do (which you will discover when you start working with it).
Good luck and if there is more questions, ask away and I'll try to reply to the best of my ability.
