Looking for a Quick Render

I am an average Youtuber, and I was thinking about how all of the popular Youtubers have Blender-done thumbnails. I just want 1 or 2 quick pictures done. If someone would do this that would be great, and I will credit him/her in every one of my videos

#1 (most important): I would like my player's skin (http://i.imgur.com/2J9bfJa.png) wearing a diamond chestplate, holding a sword in it's hand.

#2 (optional): I would like something the same as the first request, but diamond pants instead of a chestplate, and holding a diamond pickaxe.

If both of the backgrounds for these could be transparent, that would be awesome

Thanks,
Slip
