There is a better section for these types of questions. Don't ask me right now which one it is though.
You shouldn't need more that 3-5k plat to make your T1 wrist. 1050 pp for each of the container and the colescing agent. I don't know what sevrer you're on but on mine the templates usually go for fairly cheap (I think 2-3k plat tops) Also if you can get enough loyalty points theny uo can start buying bags of platinum from the loyalty vendors. Those give about 13-17k plat per bag. I have max loyalty and I can buy a bag of platinum once every 4 weeks.
Find a friend to invite you into their fellowship so you can gain aa quickly since they added the fellowship exp sharing thing.
As far as plat farming goes, try field of scale in SoD. The animals are con weak so you shouldn't have any trouble killing them. Snakes, scaled wolves, birds and scorpions. Just watch out for the named such as Darkcoil and Jcaerza the Feral (a raptor model), they will tear you a new one. 5 named animals. The named bird is especially nasty since it silences. flutter-something... Ancient Bonegrinder drops a really nice 25ac 90 hp aug if you can kill it or look for it to rot. Bonegrinder's Bauble. the named scorpion is a tiny black scorpion... something the dimunitive... can't remember. Theres also a couple quests involved in killing the animals one is collecting carcasses.
Hope this helps.
