If this customer of yours is willing to get it to North Phoenix ("Dooleyville"), then I can do it. It will take me a full 2 day weekend, if I'm provided advanced notice. I would need to know all the details in order to give a good price, but it would be somewhere along the lines of 500-600 dollars plus any parts needed. Also, I will not guarantee the motors condition prior to install, meaning that if the motor is bad and I do the swap and it doesn't run, it ain't my fault. In other words, I would install only and guarantee my labor ONLY.
Let me know if this helps and or the customer wants it done. If not, my feelings won't be hurt. Good luck!
