And more ideas are welcome by anyone .... Let's make a really good topic which can ease of searching and sortlisting efforts of recruiters of the community.
you can add an application form for members who are interested to be included in the list, something like this would make things more organized:
Username:
Profile URL:
Rank:
Services you offer:
ANN Thread/Portfolio:
Contact info:
Payment options:
Sending them personal messages may be a great idea, but we have a forum rule about message spam that can lead to a temporary ban, so my advice is to drop a meaningful comment on the service provider that you want to invite to this discussion, and ask after your meaningful post if they are interested to include their service to your topic, and if they are interested they will respond and that's the time to send them a personal invitation.
Don't send them PMs.
i second that. @henry1111 already got a 3 days temp ban a few days ago, so sending unsolicited personal messages, could get him permanently banned this time if they get reported.
