I have been dilly daddling with Wedding videography for almost six years producing 6 amatuer but complete, wedding videos. These have mostly been for friends and although I have been re-imbursed some costs as a thank you gesture I have yet to be paid. However, I have just been approached by a friend of a friend who has seen one of my videos and would like me to give them a qoute

. since, until now i have not thought of this as any thing more than a hobby i haven't looked into cost.
I have a Sony FX1 and a radio mic system to hand. I have a decent computer and Final cut pro for editing and was wondering if anybody could give me an idea of what i should qoute? and what cost facters i should consider i.e. copyright seeing as I would be charging? and also maybe what services I should offer and should not offer seeing as I am only a newbie (I don't want to get in over my head).
As I said i have done a number of vids and they have already been impressed with what i have done before

, I'm certain they would not want to pay a huge amount (and with my experiance, even though i would say i was good

) i shouldn't ask for a large payment. any thoughts and advice welcome.
any how thanks in advance,
Gary
