Based on what you're asking it would seem to me that you would do well with either... BUT,not in expediting per se. Go to your local airport and solicit the forwarders(ie;Danzas,Kuene&Nagel,expeditors- international,etc AND their local cartage agent(they will run you at a % but get you alot of volume). I used to run operations for a local carrier that did all the regional work for several in Dallas TX. and I had several"contractors" to do the a,b and c hot-shot work(extended milage, out of state runs and local"specials" (after hours,wknd,holiday).Contractors save O/T! and most local drivers didn't have the hours (or desire) to begin with...we made a couple of bucks while making sure our customer was happy knowing we could provide COMPLETE 24 hr.service. It paid VERY well to those guys,around 40 bucks a pop min. for local spcl's and 1.35+ a mile past the area a,b,c,and d guide lines!$1,000.00+ wkly chks were the norm.Obviously your loadcapacity will have a bearing on what you make. Its not forced dispatch but say "no" too many times and you don't fill their gap! BYE! 24-7 availability but you are home most of the time. Runs pay enough one way to cover both so if you find a back haul, BONUS! or if the company- does you can work out the split as you go.Make sure your p/u has a high topper if you go that way. Good luck and I wish you the best.
Keep it between the lines and take care of each other.
