An idea I had recently, is to exchange items during a repair. For instance a slicer agrees to open a container, he allows you to hold something of his. Or an artisan agrees to fix something for you, then he lets you hold something of equal value. Armor for armor, speeder for speeder, and so on. Of course this only really works if the person asking you to fix there item really wants it back.
Secondly, no matter how nice, or honest, or wealthy, a player character is, no one should be doing anything for free. At least the player who slices your container, or repairs your stinking dirty underwear should be a friend, or companion, or guild/association member. If he or she is not one of those things he should charge you, or expect to be able to call on you for a similar in value favor later. This may seem a bit tight, or petty, but that is how it works in the real world and that is how it should work in the the MMORPG. Sure I'll help you out when your down and out, but if I see you in my time of need don't be surprised if I ask you to return the favor.
Newbies are the only exception to the rule, always help a newbie, but always make them work for it. For instance if they need a coat, don't just give them the coat make them come to the bazar and sell it for 1 credit. Yeah you didn't make any money, but you have taught the newbie how to be more self sufficient, and how to find items for themself later.
