How much to charge for changing a website layout colors.. php files ..css ?

Hi guys,

i was assigned to make some changes to a website layout like link colors, menu colors(background image color changing).. edit some php files for a form..

i would like to know how much to charge in your opinion?
i dont want to charge to little but again not too much,

thank you for you time & help here!

 

I think you can charge 8 to 10 $ per hour depending on the work..

 

Well i think it depends upon the client and what kind of work they required...

 

it depends on the amount of hours you took and your hourly rate.
For me a general rule that I take is: (hours it took to do the task) x 1.5 x hourly rate
The 1.5 constant is just for business expenses -eg electricity, office rent, etc.
