re: "I don't want to post a job without having the opportunity to look at a list of Wordpress developers on your site and see their qualifications and what they charge. Is it possible to see such a list and then post a job?"
Yes.
You do NOT need to post a job posting on the site.
You can use the Search tool to look at as many Wordpress developer profiles as you want.
You can use the Browse pages to look at as many Wordpress developer profiles as you want.
You can look at Wordpress developer profiles, see their portfolios, read their overview text, job histories, see their posted rates, everything.
Here is a link you can look at. This is just one of multiple ways you can find and view profiles for Upwork Wordpress developers:

re: "That's fine. I need to see who's out there and what they charge before I post anything. Thank you."
You don't even need to look. I can answer your question right now: There are Wordpress developers available to hire on Upwork who cover a wide range of skill levels and rates. There are Wordpress developers who will work for around $5/hour, and there are Wordpress developers who will work for $100/hour or more, and there are all types of people in between.
You may wish to experiment with different pay levels and different levels of experience, to find the the developers who work out the best for your project.
Always remember that if you hire a Wordpress developer who charges $100/hour, and you hire another Wordpess developer who charges $5.00/hour, the one who charges $100/hour may be the one who costs you the LEAST amount of money to complete your project. Or, the one who charges $5.00/hour may cost you less. Or maybe somebody else, who charges $25/hour would cost you less. That's not something you can know beforehand.
Also, keep in mind that it is possible to hire freelancers using fixed-price contracts. You should always start with small tasks to test how a freelancer will work out. Never start with a milestone payment for the whole project. Once again, a freelancer who says they can do the Employee Listing page for $100 may be less expensive in the long run than a freelaner who says they can do the Employee Listing page for $500. But you don't know that for sure. What if you can't use the $100-quoting freelancer's work because it doesn't fit the style or needs of the project, and you end up throwing it away?
If I hire 5 different Wordpress developers to work on a small part of my project, then after that experience I will have 5 choices about who to continue working with. Eugene did terrible work. Peter did awesome work but he is so expensive! Nancy never did anything. Frank did really great work at a very low price. Sandra did even more impressive work, but she is a bit pricey. I decided to have Frank do most of the work to finish the project, but I kept Sandra on the team as well to do the most complicated parts. This way I minimized my cost and obtained my project with the level of quality that I need.
Manage your project intelligently and proactively. Monitor the work that freelancers do and stop working with any underperforming freelancers. Continue working only with the freelancers who provide you with the best value for your project. Never assume that just because you hired a freelancer that it means you need to continue to working with her. You can close the contract on freelancers at any time. Put yourself and your project first. Don't get fixated on any one freelancer.
