How about no? It's unlikely you'll get any other replies so i'll post and tell ya what's what.
Skinning is very hard to do well. I like to skin, but my work is never truly original art, just recolours and small modifications.. the easy stuff.
Download Half-Life Model Viewer and open an ESF model. Go to Texture, then Export. Save the file as a BMP in your models folder somewhere. Now open Paint Shop Pro, open the BMP, and Increase Colour Depth to highest quality. Edit. Reduce quality, Import into HLMV, Save, play. If you dont understand any of these stages, I suggest you get all the software and toy with it until you catch on.
