Well, from the initial desire to make the figure to the final product can literally take years. Sometimes I’ll want to make a character, but the means of making it won’t exist yet, or might be too costly at that time. Other times I’ll have a hard time figuring out how to proceed with a project, but months later I’ll have inspiration as to how.
Assuming I have all the materials, the average figure might take a few days to several weeks depending on my interest in the character and interference from real life. Total man-hours spent might range from one to 30, depending on the complexity of the project. As for money, that’s hard to say. As an artist, I keep a large supply of materials on hand at all times. That includes “fodder,” or figures bought with the express purpose of using them in future custom projects. In most instances, I can go to the fodder boxes and pull what I need to start work, without having to purchase anything at that moment.



Easy: A simple parts swap. Little if any paint.
Basic: Some modified parts. Mostly a new paint job.
Moderate: New and modified parts.
Skilled: Lots of new and modified parts. “Frankensteining” often involved.
Advanced: All of the above, plus a great deal of original sculpting.
