You have a cleric and worry about money.... Hit 49+ and rez for donations. You'll make money and make a name for yourself if you are just doing it for a donation of what the character can afford and not refusing to rez if they can't pay you XXXp. Team up with a druid/wiz friend and you can travel. Many ppl will pay you several hundred pp to travel to a zone and rez 2-3 bodies for them.
If you insist on spending time leveling up another toon instead of playing your main just to get gear/money for your main (as opposed to leveling an alt for fun), necro would be best imo. Like someone said earlier, mages are pure power, but they don't have the versatility of a necro in breaking camps (FD). Plus, you can charm in undead zones as a bonus
