Unusual to have the front bottom out unless you have a damaged shock absorber or two. Usually you would see a fluid leak on the side of the shock. Only real fix is to replace the springs. These vehicles commonly have the rear end lower than the front and for that the simplest and cheapest and most effective is to add a leaf spring at the rear. Cost will be under $150 parts and labor at a offroad shop.
Avoid the Midas types of places and go to a place that specializes in suspension work and have them check out the vehicle thoroughly.
Good shocks overall are the Bilstein's in the 4600 or 5100 series.
