Recommendations on a Field Processor?

Hi all,

I am working on a little project to convert my Ponderosa slash into a debarked wood chip to later be used in a cement mix.  I would love to get these limbed and debarked right after felling, and everything I see is either too manual or WAY to big (and $$$) to buy.  Is there an intermediate solution that is affordable, or does anyone recommend renting for something like this?   For example?

Afterwards, the chip size I am looking at ranges from ~1/2" square to ~1/4"x1", and I would like to try to utilize as much as possible of the white wood, not sure how small diameter things work for things like this.

Any help on this is very much welcome.  Do to the particulars of my process, I need to do everything while the chips areas fresh and green as possible, so speed of debarking is important.

Thanks guys.  I am usually able to search and ferret this stuff out, but my searching skills let me down on this one.

Regards,
Jeff
