To Jessica's question: "How to approach professionals about possible mentorship opportunity?" If this is someone you do not know, see if someone who knows them is able to introduce you. If that isn't possible, reach out to the person after doing some research on them. Let them know what brought you to want to connect with them and ask they have some time to speak with you about something in particular. Asking someone to mentor you is a little awkward but asking someone to coffee to talk about their career path and if you could ask them some questions on a situation that you are going through specifically is easier.
