(LS)+Missions

Hi, a friend and I just got back on here after close to a year gone. Looking for a LS for leveling and doing missions. Not the most exp. players but, I have a Sam. at 75 and some other jobs started but not fully leveled and the friend of mine has a puppet master at 63. Really would like doing some of the missions. At the same time while I help him party and level his pup. to 75. Anything would be greatly appreciated even if its just advice. -- Thank you in advance.
