Determine CRC calculation from dataset

I have a binary file (4k bytes) that has been stored using some unknown CRC calculation. I do know that, once decoded, it contains 3 particular bytes, but I cannot find them inside the data. I need a freelancer to determine the CRC system used in order to decode all of the data inside the file and find the bytes that I am looking for.

I have attached the binary file. The 3 bytes I am looking for are 8E 01 D5. They should be close together, once the file is decrypted.
