Fix: Rig and Paint Weights for character's elbow in Maya

I need a good rigger in Maya who has a good understanding of anatomy. I have a character and it has rigs and existing paint weights already but the only problem is its elbows. I need someone who can fix the elbows paint weights. I want the elbows to behave like how a real elbow would, especially when the lower arm is closed to the biceps.. etc. Please find attached photo of the elbow. On the picture, the inner parts of the skin (near the elbow part) are looking weird. I've encircled the area. Budget for this project is only $10-15 per hour as you only need to fix the elbow areas of both arms. I guess, this won't even take an hour to do so. Bidder should work this project for ONE hour only, but is open for any revisions if I'm not satisfied with the changes for the elbows. Thank you.
