To each their own. After getting a 2 day ban a few years ago on my main on OSRS, I haven't opened up a bot client. I've trained and improved my account on my own and the game is more enjoyable this way.
I do like writing bots though.
Some more details would be greatly appreciated.
Please tell us how you expect the developer to work. You give him specifications of the software and then he/she makes it? When are you paying out? PayPal? 07GP? You've not convincing me (or anyone) right now.
So you get at least 65% when the programmer, the one doing most of the job granted you want someone experienced in Java, SQL and PHP, gets 35% at most?
Pretty much.
Not worth making a bot for this.
There are some mini-rooms throughout the basement that have a behemoth where you can put your adult/wily cat to fight. When the rat is killed, you'll get a 4-dose of whatever color the behemoth is protecting. You can do it as many times as you want.
