I need help to install & activate Facebook PIXEL correctly

Recently I created an online store using WordPress & WooCommerce. I have been using a plugin called "Facebook for WooCommerce" which allows me to auto synchronize products from my store to a Facebook page. Previously I had a Pixel created by another freelancer but I can't use it in my new shop which is a subdomain. Then I created another Pixel which also not works. Also, I verified the subdomain but it does not show while creating ads.

White, I say "Not Works", which means that I'm not able to create ADs and those pixels have issues. For both Pixels, I found the same issue "No Conversion Events Available For This Pixel".

So I need a person who has extensive knowledge in Facebook marketing and a little bit about WordPress/WooCommerce shop. You don't have to be a guru on WordPress or WooCommerce because I can help with that, you just need some familiarity with WordPress.

The end result or my expectation is as follows-
1. There are no errors in my Pixel
2. I am able to create ads for the Facebook Product Catalog

The interested person should be able to talk on Skype after hiring and solve the issues. You don't have to teach me anything, nor I am interested to learn. The Skype consultation is required to make the process faster and easy to understand for us.

Bangladesh, Pakistan & Indians are most welcome to bid.

Thank you
