For that you can buy a used decked out john boat style Alum. rig on a trailer no problem.
Pond hopper type plastic boats are super stable and with a 30lb. thrust trolling motor will get you around just fine. You can get into a brand new one, with a trolling motor, battery, and a decent graph for about $1500. Add a little trailer and you are at $2500 or less. I used to fish from one of these and fished, Fork, Roberts, Toledo Bend, Monticello, etc.. you just have to use your head and be safe.
John boat has more room, plastic boat is probably a little cheaper.
See you on the lake and have a great day!
