I have hundreds of certificates that I need to make electronic copies of back and front. For this project I would send you a pdf file with all the certificates scanned back and front then you need to split the one pdf file into one file per certificate and then label each file with the certificate number ( or other metric on the certificate. Splitting one pdf into many smaller pdf files is possible with Adobe Pro. When you bid please bid for 500 certificates and let me know how long it would take. If you do not have Adobe Pro you can include the cost of this is your bid but please let me know whether you have it or not.
