Ask LOTS of questions here.
Pay close attention to who gives good and generous answers.
You will see that different people have different answers and different styles. Different answers does not mean that one is wrong but a lot of the answers that you receive will not be "best answers" in general or not be the "best answer" for you. Still, different answers are informative.
Seeing a diversity is important.
After you have asked LOTS of questions you might realize that someone has a style that you like and gives answers that you believe are valuable - and get lots of thumbs-up from members. That is when I would select a person for paid consultations.
All of the people who I have paid for consultations have first demonstrated to me in forums that they know their stuff and have respect of their peers. After this type of screening of consultants I have not been disappointed. However, if I would have hired people without this screening I would have been disappointed many times. Why? Much of the free advice given on forums is bad advice or not good advice for you.
Read the profile of anyone who you consider hiring. Some are available for clients. Some are not. Go to their website if they list one and look at it critically. You can get fantastic assistance from many of the members here, but be careful to be sure that you get the right person for you.
Good luck.
