You'll want to check in with one of the Dallas mods but ...
(1) Submit your info to the staff at
dallas@eccie.net
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. No minimum requirement but the stronger the reference, the easier it is to verify.
(2) Your website can be either your ECCIE profile, your P411 profile, or a third party website.
Apologies to the local mods for jumping on this question
