Web Developer needed

Websites are already set up and functioning with the payment gateways I just need someone to attach the pdf document to each or 9 training courses for download, make sure payment gateways which is clover are working efficiently for all 5 websites most of them are already but just want to be sure. Some web links content pages on a few sites keep changing back to the sign up page for some reason this needs to be fixed. There are also some edits like correcting misspellings and replacing background photos on a few web pages. This project is 85% completed I just need someone to do a few fixes to finalize everything to go live
