PCB Layout in Altium

We have an existing PCB layout where the top/bottom layers needs to be modified. The new top/bottom layers must be copied from a reference design and slightly adapted to match the size of the PCB. The top/bottom layers contain high-frequency RF structures so they must be copied with care, but no RF design is required. There will also be some re-routing of the SPI traces in the inner layers to match the new top/bottom layers component positions. We will provide support and review to make sure the final layout is correct. More details is provided in the attached document. This project must be completed urgently so only apply if you can start working on this project right away and complete before end of week. Please add the word ALTIUM at the top of your proposal to confirm that you have read through the entire project description. Let us know if you have any questions. Thank You !
