The first thing you need to do is get a halter and lead on them. If they were at my house I would ride into the round pen on another horse and rope them and teach them to give to the rope then move into a halter. I would then get them to lead with either front foot, then the hind feet. After I can lead them from any foot I can be pretty confident that they aren't going to kick me or rear up and paw me so I can start grooming and handling thier feet. At the same time I would be saddling the horse and getting it ready to be ridden. Usually with unhandled horses it takes me a week to get to riding them. Some take only a couple of days and one I trained took almost two weeks so it will vary some.
The first rule is to stay safe. If you need to hire help then do it before you or the horse gets hurt. No horse is worth ruining your health.
