Want information about director visa

Hi everybody. ..
I am a pakistani citizen and I owned a sdn.bhd company here....even I took a shop on rent and have a local Malaysian staff at my shop..
my question is that how could I get visa of director on behalf of my company in which I am a partner of 50% with a local sponsor. ...while the company worth is one million. ....
I already have got dbkl licence and all documents are complete which are required to apply a visa ......
now have I to apply my visa by the help of some agent or either I can get visa by applying myself directly. .....
and is it easy to get visa directly without any agent ?
Please I need proper guidance by any one who knew the immigration laws here....

I am on a multiple entry visit visa currently. ....
