3D Gun Modeled and Textured for Video Game

I'm looking for a Laser/Beam weapon to be modeled and textured(realistic art style). I have included a concept sketch. The gun is alien and futuristic in origin and can be handled by humans. The price for this job is neg... and I have several weapons to do for future work if the right modeler is found. The timeframe and turn around is within the next week. Speed is important, but not over quality. Texturing the gun can have some design from the artist...but can be discussed in more detai.
