Ok you basiccly want us to make a map so you can claim it as your own?
heres my input...but be careful wat you do, b/c im not making your map

~Bound Defense~
You bound a certain level to gain cash to buy guys for a defence level after that
level 1
~bound- A simple one, like marines dieing in a row or something similar
~defense- The reaver is overused, lets go...lurker, defend against the lurks with the cash from the bound sequence
Level 2
~bound- something slightly harder than lvl 1
~defense- Shall i say kerrigan? (zerg of course)
And so on and so forth like? dont?
well to bad, but theres my input

(if you use this idea, put my name in the briefing)
