photoshop work pay rate

[liaj]

i posted this on another thread here but i wanted to see if i could get more responce here

i just got a new job, not as a graphic designer but in a commercial photography studio doing photoshop work. its not a full time job, more like a contrator job for now retouching commercial photos. they said they were 'very impressed and were hard to impress'. so they asked how much i want to get paid per hour and i have no idea! has anyone else had a job like this or have any idea how much i should get per hour? basically what i would be doing is working on the photos they take (commercial products) doing stuff like color correction, removing dust and specks, just general making the photo look nice. they said if i got into really heavy manips then we might do another price...so how much should i ask for?
