COMMISSIONING CUSTOM RESOURCES (ON A BUDGET)

Hi all,

So I've gradually become more comfortable with RPG Maker XP to the point that I think I'd like to try and invest some time in a larger project. The thing is I really want to build something with unique resources (ie: sprites, tilesets, music, etc). I've already found a wonderful composer that's making music for me at a very reasonable cost but since I'm paying out of pocket I'm wondering if you all knew how much I could expect certain things to cost.

Namely:

Sprites- I know a local sprite artist but he's an exceptionally busy guy and so I know that I'm going to want another sprite artist to help. Does anyone know of any good artists and moreover, how much can I expect such services to run me?

Tileset- Same as the above. I want unique environments but I'll need to find someone to make them for me.

Scripts- As far as I can see I only need one unique script right now. I have some ideas for modifying XP's basic turn-based combat. Any ideas on how much hiring someone for that might cost?

Any pointers, ideas and suggestions would be much appreciated!
