When I started, I applied and uploaded to every site that let me in. I didn't (and still don't) see the logic of just starting with one, gathering data, and doing all your homework before you decide where to sign up next... why not be selling everywhere you can during that time?
Sure, your particular port might sell 1X at site A, 2X at site B, and 3X at site C, but where's the logic in leaving out site A, unless your numbers are so low that it doesn't justify the effort in uploading (I recently made that decision on CRE and VEER).
So my advice: send to every agency (at least the 7 that matter, and to me those are SS, IS, DT, FT, BigStock, CAN, 123) and if you determine some aren't worth the effort, axe them.
