I know this is a bit of a nebulous question but I've never done a job like this before. Usually I just do small layouts or straightforward designs. This is basically three different sets of labels for one company that sells oils creams and homeopathic stuff. I need to take one of their logos which looks like a complex stained glass design. I need to take a piece of it and redraw it with smooth lines and also alter it to suit. For example there is a stylised person on it and for the hair products I will change the hair or I might change the position of the arms. For other products I will put some stylised and also 4 colour graphic objects in her hands. (See image.) Another part consists of making a fairly simple logo and they have a good idea what they want so I only have to redraw it and play with the proportions. It will be mono colour. Those first two are difficult enough to know how to quote but they also will want me to make up labels for different size bottles and this will be an ongoing thing. They want it all fairly quickly. I have not the slightest clue on how to go about quoting this especially as it will be ongoing. Any clues from those experienced in these things is appreciated.
