Where to go as a owner operator

Hey guys I'm in a weird situation I have always worked for myself and only hauled my own products I have never used a load board but I was wanting to start hauling for hire and looking at where to go and my dot numbers have been registered since early 16 but have never needed a mc number I would also perfer to use my hopper bottom but willing to look at other things any advice on where to look I'm waiting for a call back from Oakley but I dont think that they will want a truck over 10 years old hauling for them also my other problem is going to be I have been driving for about 10 years but ran a class A for a majority of that time and just got my cdl class A about 6 months ago because when moving to a new state they didn't have a similar option so I had to go to the cdl
