Hi!

I'm currently developing a freeware RPG in a good old SNES style, and since I honestly can't draw anything I need someone else to create the graphics for me.
The game is to have an medieval theme.

What I am looking for is:
- Ground tiles(grass, snow, desert, city, mountain, water, dirt road)
- Building tiles(walls, roof, doors, various exterior)
- Characters (four directions, animated walk and attack would be appreciated)
- NPCs (four directions, animated walk would be appreciated)
- Monsters (any kind of monsters really)
- Items (Weapons, armor, potions, rings, food, etc)

Basic groundtiles should be 48x48.
Characters and NPCs should have 48 width and up to 96 height.
Monsters can be mostly any size, as long as they are not bigger than 250x250.

Just ask is something seems unclear or there is something I forgot to mention.

Hopefully someone here can help me out :)

Creating the whole thing from scratch.
May become opensource if I decide to.
Language? Are you referring to programming language, or in-game language?
In-game language will be english.
Programming it in Visual Basic, so Windows is the natural selection.

Forgot to mention that it's top-down view and not isometric.
