.. For an 'artist' with my ''''expertise''''? Some of you guys here might have some idea of what the things I make look like (and if you don't you can always take a look), and even though I'm planning to ask others (and ze rest of ze interwebs) for advice, I thought, why not Zoidb.. Newgrounds?
A person has asked me to do a rather large piece of work, a sitting up-from-knees-portrait of her and her boyfriend, with psychedelic aspects in the background. The work itself should be poster format (A2), she likes it to be done in watercolour (but I can actually add digital work too if I want, or a mix of a lot of things), she wants some decent amount of detail, made to fit the personalities of both of them, like holding books that they love, adding records that they listen to, .. All of it can have an air of humour and mock 'aristocracy'. As far as I know now the piece isn't needed anytime soon.
Now, I never made a piece of work that needed that much attention, planning and serious face, so I don't even know how long the piece is going to take.
Now a little info about me: I don't have a steady job at the moment, but one should/could be coming up. I am going to need to buy some new stuff to realise this project (like actual aquarel paint instead of kiddie watercolours), I'm probably going to have to do some real-life-observation/photography of the peeps and don't forget, I'm nowhere near an actual professional.
So my question to you guys: Have any of you had similar things made/made similar things? How much did/would you charge for it? How much would you be willing to pay for something like that (considering it's made by me, be that good or bad)? Hourly rate or fixed price?
I know I'm the one who ultimately knows best, and I hope asking such questions isn't against any rules, but I though some advice from here could be well used.
