Looking for a RS Companion bot

I need a bot which is able to sell large amounts of an item, automatically checking lowest selling price and sell my items for lower. A bot which is able to cut margins. I think it shouldn't be too hard to make it to work on Runescape Companion. I am willing to pay good money for it.

 

Sounds interesting, I haven't heard of this app before and I think it would be great to support this within our bot.
