First off,I am not an "ADC" trapper.Its just that I cannot possibly cover more country than I do during fur season,and people still have beaver/coyote problems.
I don't know what your level of experience is,take that into consideration when you set your price.I base my price on being able to COMPLETE the job.
A four acre pond is very manageable,but if you are talking about a thousand acre flowage,I wouldn't do a whole lot of suggesting getting out every last beaver.
I prefer to "crop" beaver,but a lot of landowners(with all kinds of new "lakefront property)LMAO,just want them GONE.
Like Bog said,if this pond is a gate to other trapping,or even a means to get your name out;thus scuring other property,take it into consideration when setting your price.
If you are just getting started in ADC,you are better off starting low while your learning curve catches up,if you come in high-dollar and don't satisfy the client,your name will spread like a bad rash,with about as much enthusiasm.
