Hached WP website, non-technical user

Late last year, my WordPress based website (I also have a WordPress blogsite) was hacked, with a redirection code to a pharmaceutical supply service. A colleague whom is also my webhost has, apparently, been in contact with them in order to track and clean the site. A partial move was done, in that a new password was supplied but it still redirecys from an archive dpage, not from the main page as before. I’ve installed Wordfence which has blocked and informed of attempted logins but, of course, hasn’t cleaned the code.
I am by no measure technically illiterate but the methods offered by WordPress to do a full un-and re-install are beyond my skills.
The site name is “www.awheelthing.com”, any and all assistance in finding the code and cleaning it is deeply appreciated.
