WordPress Customer Purchase Flow Testing & Setup

I need a professional to thoroughly test the customer purchase flow on my WordPress site, and set up any missing elements.

Tasks include:
- Test subscriptions functionality
- Verify customer portal setup
- Check the status of the cookie message

Additionally, I need an assessment of my Stripe integration as I'm uncertain whether it's partially set up or needs a full setup.

The ideal freelancer for this project should:
- Have extensive experience with WordPress
- Have knowledge about Stripe integration
- Be capable of setting up the cookie message
- Have a keen eye for detail to ensure all elements of the purchase flow are working smoothly.
