Is it standard to reduce your rate if it means you're learning a new skill for the job? E.g. I am soon to be taking on some animation work for a client of mine. They did originally ask if I knew of any animators but I said I'd be happy to give it a go myself and that I'd just need to do a bit more practice beforehand (I'm a graphic designer who has a little motion experience).
I was thinking of capping my cost at a certain amount, or working for a reduced rate.
Would that be pretty standard to account for the extra time it will take me to produce it? I feel it wouldn't be right to bill them my usual rate otherwise it would work out a lot more costly for them to go with myself over someone more experienced.
