Need RS2 Autocalc for trading

I was buying and selling coal. Everytime a player came to me to sell coal i had to bring up my calculator to see how much i have to pay.
So..is there such good programmer to make a calculator that automatically calculates how much i have to pay. No matter whats other player is giving to me. Program just checks the number of item in first trade slot then calculates. It would be much easier and faster to trade. It would be nice if program has always on top too feature too
Here's a pic what i mean (made with paint! thats not real program): click here

 

My Client (LSK) has a Merchants Calculator with easy to add "k's" and "m's", it's worth checking out, if you DONT like the client, just copy the file (LSK Lookup.exe) in the data folder and then uninstall the client, and just keep the Lookup/Calculator.

 

Ill give it a try. i post in a few mins...

I'd like if the price check had been more automated.
No entering amount of items, auto calculate...

But nice client anyway

 

or you can stop being lazy

 

yeah, but i can give 500k the one who can make this, like i want it.

I think there aren't anyone who will make a program like i want.
