Where to find Quality "OTR Only" Dispatchers for Box Trucks

We’re ready to take our box truck business to the next level with OTR loads out WEST at 2 to 3 weeks at a time with 2 to 3 days off in between. We have the 26 ft. truck… we have the OTR experienced driver…
However, we don’t have a solid, proven dispatcher that understands the seriousness of keeping a professional driver (…and chief breadwinner and bill payer) of his home consistently on the road.
Any recommendations anyone can provide? (Please, no new, start-up social media dispatchers…) but again… professional, proven and understands the logistics of OTR box truck driving.

Thanks in advance!
