Ok, after talking to Dexter axle, then Orscheln (who makes the brake levers and hardware for Dexter), I found the company who actually makes the cables. I emailed them my specs (as far as I know them, I won't be getting my trailer until the end of May) and asked for a rough estimate for two levers, cables and mounting hardware. You'll have to make your own lever mounting bracket, depending on how you are going to mount them on your trailer. The cost for my Teardrop will be around $225 for all the parts which I think is really fair for what I need. I will be using the Dexter K23-086/087-00 plates with the parking brake option.
Here is a link for a worksheet and detailed information for sizing your trailer:
