2012 21 SE Trailer recommendation wanted

I have a 2012 21SE (160 hrs, now asking $30500) that I am selling and it has been on the market since last July and not sold. So I am thinking of getting a trailer and adding the cost to the sale price to help speed up the sale of the boat.

Does anyone have a recommendation for a moderately priced trailer that they know will fit a 2012 21 SE?

Also, curious as to opinions about whether you think this will help sell this boat.

boat is here
