New to the HotShot World, would a dispatch service help?

(sorry for the long post)
My husband & I recently made the move from dump truck to hotshot. We have gotten pretty steady work from a local company but they never seem to have a load coming back - Atlanta to PA/NJ is a typical run - so we are getting a lot of "dead head" costs. I work full time so I can't really help him learn the load board situations while he is on the road. We were thinking about connecting with a dispatching service & even reached out to one when my husband was given a card at a truck stop.
This particular dispatch service charged 6% - 12% depending on the rpm, wanted my signature on a blank piece of paper for load confirmations, my bank account info & signed permission to access my account every Monday to deduct their percentage. I was only able to find a Facebook page when I did a company search when I saw their carrier packet & what they were asking for. It just sounded like a huge scam. When I questioned it, telling them that we too were a small husband/wife team that I had to protect us 1st, that we work through a factoring company that they would only invoice them for our percentage of the load & they could get their percent when the shipper paid them. Also, their big sell was the driver "just had to drive" & they do all the paperwork. Well, I told them that wasn't an issue for us because I do the paperwork & my husband drives. Their reply was that they were burned by a husband & wife team who was booking loads without their knowledge - which I thought was strange because it sounded like they were just upset about not getting their cut but IDK. Also, they claimed to have been burned by a factoring company which is why they use a CPA firm to handle the deductions. Given that I obviously had reservations, you would have thought they would have at least provided the name of the CPA, but no. We agreed we were no a good fit for each other. This was just too many red flags for me, I mean I'm new to the HotShot world not stupid. And if this is the norm, please feel free to call me stupid
All that said, 1st, was I wrong to be skeptical? Is this how dispatchers work? 2nd, should we look for a broker service or another dispatch company? Any advice / suggestions will be greatly appreciated! Thanks in advance!!

 

My husband was at a truck stop and just walked up & gave him this card. He said that they were great, always kept him loaded, etc. My husband said this guy acted like this company was making him a mint! I want to put his name out there as a warning but I don't want to smear a company's name if he is technically legit with questionable business policies. Their Facebook page has only (1) review & of course it is praising the company. I'd hate for anyone to get rooked by this guy.
