Boat question

[Duck Butter]

I am 'forced' to buy a new boat! The boat is for working purposes, and the boat will have to go through shallow water at times. Just got the go ahead for a surface drive or a longtail type motor. I have about 10K to spend on boat, motor, and trailer. No need for speed or anything, but jsut something big enough to push a a 15 - 16foot flat bottom boat (possibly an Xpress). Like I said, I will be working out the boat on occasions, so need a wide flat bottom for gettin in and out the boat and carrying multiple people and lifting heavy things over the side at times. I have used go-devils in the past, but what about the new surface drives? Prices? I need the experts to design me a boat
