I'm looking for a pastebin script that handles mIRC Script (for free), could anybody point me in the right direction? (ive got access to php and mysql so thats not a problem).

you could write one and use udp in the php to send a packet of info to your mirc script and use that to paste a link and what not

if i knew php i would write one, but i dont so im asking

If nobody finds one, I will write one for you. I cant promise a great deal of fetures to you though.
