Project: Fire Emblem Epics

Hello, I am in need of a terrainer.
As the title already said, this map is 100% based(Expect for turnbased-ness) on the RPG-Strategy game Fire Emblem.(Sealed Sword / Blazing Sword)
For those who doesn't know the game, the map features the following:
- Completely customized Combat-System: damage/hit/evasion/critical which affect each other in an unique way of calculation. (yourHit = yourHit - foesEvasion, yourDamage = yourDamage - foesDefense etc...)
- Stats/Weapon-System: 8 Hero Stats combined with the Stats of the equipped weapons affect the combat-stats.(Damage/Hit/Evasion etc...)
- Support-System: Individual Characters(Heroes) get closer to each other by having Support Conversations, thus increasing their relationship to each other (Support Level) which at last gives bonus combat-stats if they are in range of each other.(bah, this one is hard to explain, you would need to know Fire Emblem)
- Over 35 Classes and over 65 Characters with individual Stat Growths (the percentage to get a certain stat on Level Up) and relationships
- Magic-System: Spells are based on the equipped weapon(Books), each book has an own spell, which only can be used if equipped.
- 100% JASS enhanced
The gamescript is already finished, so all it lacks is a terrain >>;
I also already have a litte scetch how it would look like, and all I can say is: It does not look too complicated, details can come later, since the map is being on hold just because of that.
Why I don't do the terrain part myself?
Well, let's say I tried, and I failed. (Maybe I just lack the talent.)
