Leaf Springs gone bad on my 2009 Four Winds 28A

Thanks for the info and tips everyone. What type of cost range would you estimate I should expect to pay if I take it to one of the local shops here? The sense I've gotten so far was around $2,000. I'm hoping for less than that. I'm pretty handy with tools but not comfortable doing this type of job so would definitely need to hire someone for the labor.
