I have a friend that has a 1988 24' Searay Laguna with a trailer. The boat has the original twin 135's on it, but they run pretty good and the boat overall is in pretty decent shape. It's a center console with a good amount of fishing room, a T top, and it also has a little head compartment inside the center console.
Every once in a while he thinks about selling it. I don't know what he would want for it, but I'm sure it is less than you are looking to spend which will leave you money left over to do what you want with.
If you're interested, I could ask him if this is one of those times that he would be considering a sale.
