Update Altium schematic/layout for new MCU

We have a PCB with STM32F030 20-pin and need to switch to STM32G030 20-pin. The job involves redoing the pin-out and updating the schematics and layout on Altium. We are looking for someone with good Altium skills for who this job should be very quick. This may lead to more work if interested to keep working with us. Please quote how much and how long you expect it to take. Thank You !
