This is what I do for a living, please keep that in consideration.
I will only consider you for model test if you are of agency measurements (you do not need to be signed). I may consider you for editorial work only if you are agency represented, and are experienced; or we have tested prior, and I know you can "work it". All models who are agency measurements that contact me will be put under my consideration, but I may not return all messages in a timely manner, due to my very limited schedule.
If you received a friend request from me, it is NOT random. I've looked at your port and I love you and your work!
