Smoking wood source ??

Hi

I got a cool Smoke Hollow brand 38 x 20 smoker. I'm starting to do lots experimenting etc. Burning everything from twigs off my Persimmon and Orange trees to  Rosemary, Sage  and Orange peels plus rice and tea.
Of course I've bought some bags of wood chips. These can be a bit expensive. Does somebody sell chips In bulk or does anybody have a source of  fruitwood etc.

Thanks
Kirk

I have some bags of mesquite you can have.

If you live near any vineyards they are pruning right now. They work great.
