Hey Megan, Im pretty sure you have to submit your info for verified provider status and then you can attach your reviews and do a showcase.
Submit your info to the staff in your area.
1. website address (your website or advertising site)
2. referral from another provider or hobbyist
3. links to reviews from recognized members (any site)
Any combination of the above requirements which will sufficiently establish you as a legit provider will be accepted.
The verification process could take 24 to 48 hours.
I found the above in the welcome threads
