I was asked by a multi million dollar company to do some corporate shots. I have done work for them before and they are really amazing to work for. This project was to spend a whole day shooting ALL 500 employees at their local branch. After 7 hours of shooting the work day ended and I went home.... I was NOT able to shoot everyone, and oops, they didnt think about the 30 people on 3rd shift. Could I come back the next day at 5:30 am... (I KNOW!!!) So I obliged. They did not offer any extra money. Now I have agreed to come back THURSDAY to spend another 3 hours shooting the rest of the people that I missed last week. UGH My original qoute was for ONE FULL DAYS work..... How do I go about asking for extra money without sounding ungrateful? I DONT like rocking the boat and have a tough time with this since they treat me so well. DO I just suck it up and finish the project and next time charge by the HOUR not by the job??? Grrrr.... HELP!
