Pay Rates

From the last couple of jobs I have had outside of Uni time such as the wedding video and the Ministry of Sound video, I have had to sit and have a think about how much I am charging people and am I charging the correct amount. At first I knew that I would have to charge cheap rates as I would look stupid turning up to my first wedding shoot charging 600 pounds and handing over a piece of film that wasn't worth what they paid. For my first wedding, I charged 200 and I feel good that I have put together something that a lot of people have told me that it is worth the money. I no I have probably lost out of money as its took me a very long time to edit but allows me to go to the next wedding and charge more knowing the quality of work that I will hand over will be worth what I am charging. For the my next job with Ministry of Sound which is on the 6th June, I am getting £150 which I am very happy with but I think I should limit the time I spend on the edit to ensure I am earning a decent amount for the amount of hours I am spending on the work. Last time I spent far too long going back and forth changing bits and bobs which meant more hours I was spending messing around, I was losing out on money.
