anyone an expert in java ?

Looking for someone who can make me a bot for runescape that runs smoothly and fast. most of the bots out there are shit and super slow. im more looking for a bot to make runescape money not just skilling but something like for instance lets say buying stuff for cheap and sell for higher in the GE or off real players. if this is possible let me know, or if u have a bot that can auto fight and pick up certain items that would be great like i said there are bots out there but they are so slow and a lot have errors after 5-10 minutes. i would like something very simplified, an auto typer would be great too as all the ones i've seen do not work for mac and are only trials.

The bot is only as good as the API. If the bots are shitty / slow it's likely due to whatever bot the implementer is using. Asking somebody to write an API for you is not going to happen since it's a fuck ton of work.
