I am a Union editor in Los Angeles, and the Union base scale here is $2365.00 per week, with lower scale for smaller budget productions (they go as low as $1585.00). I have worked on productions both union and non-union that ranged from $1500 (low on the totem pole cable networks) to $3000 (network reality TV, Union Narrative TV) per week.
But, I am in Los Angeles and this is THE market…plus costs out here are high.
What you need to do is fine out what the median is for your area.
Oh…and the edit system has NOTHING TO DO with your rate. They are hiring you for your editing ability, not for your skill with an edit system.
