Vintage Curtis Air Compressor

Hello All, I'm back again and need to know if there is someone out there that will rebuild my general electric motor that is running the Curtis air compressor. The motor starts off great and then after about one minute it will start to go super slow , then almost stop after about three minutes of running trying to fill the tank. I would need the total amount of dollars that you would charge,  to include shipping and the rebuild. You can email me back at [e-mail], and I will give you all the Info> that you need. the motor is in some of the pictures that are posted with this email. Thank you.
