I think this is sort of choose two out of three - solo, XP, good loot.

Your gear is certainly very good so you have more options than the average 56 monk. One thing you could try to do is grab a 'Midnight Mallet' and 'Reaper of the Dead' to throw in a tink bag. There are a few camps where monks can handle the PH's easily. However, once the rare mob spawns they crush you. Midnight mallet gives you 35% slow and reaper can give you a complete heal. Again you'd be dropping some plat on re-charges so it's not necessarily worth it to do for a chance at KC level items but if you could do it in Velks or HS could be worth it.

There are camps that allow you to make some decent platinum without having high value rare items. These tend to be an issue for monks unless you have a ton of bag space. Think items like ore, fine steel, armor gems. They can really add up if you're willing to make the trips to the bank or EC. I'm always shocked at how many people ignore stuff like that or let it rot.

Finally, XP is super valuable. I leveled one char to 60 at raptors in TD (made 0 plat), one at bear pits without looting anything (made 0 plat), and one char doing bats and bugs (I probably made a total of 1k total off the golden chitin bracelets and druid BP's there). But at the end of the day people pay extreme amounts to get PL'ed so if you're doing it yourself + solo then you're saving money rather than spending it. Once you're 60 the world opens up to you for plat earning.
