I need two 3D human figures modified

Information for the business: This is a technical modification rather than creative work
Design details: Two 3D human figures were created and posed in Poser, then converted to individual 3ds files as well as SketchUp files. One figure is clothed with the correct head, hands, posture and pose, but needs to be unclothed - the 3D figure has no body under the clothes and so a body must be added, merged with the existing parts, and the clothes deleted. The second figure needs only a small revision in the neck area where the modeling is awkward. This is a rush job. No images from the job may be posted in any media now or in the future.
Target audience: N/A
Ideas for the visual style: Style to be consistent with existing files
Things to avoid: Problems in the final files that create technical issues in subseqent stages of work
Preferred colors: Colorless; white
Extra notes: I am looking for someone with immediate availability who is adept with posing 3d human figures and converting and combining files (especially including 3ds) who is able to combine an existing head and hands and pose with a compatible body at the same level of detail. I need this work to be completed by Monday morning (US Eastern Standard time). I also have a second figure that needs a minor revision.
