Just want to know when setting up a graphic firm, what and what should be the services...
i use photoshop to the level of the intermediate, i'm not yet an expert, but i think i can manipulate and make things work in with the software.
so pls anybody reading this, i just need an answer to the question i asked.
When starting a graphic firm, what are the sevrices i should offer.

Photoshop is not the only one application that You'll use , if You wanna run graphic firm. There's also needs for some vector oriented graphic appz, like Adobe Illustrator,etc...

Adobe has also InDesign.

You can offer services like web design, print design, illustrations....

But, IMHO, only Photoshop is not enough, because You will be restricted and limited in Your job.

Yes - There are many medias you will want to think about to get an edge in your business.

Web, Print (offset/digital, screenprint or flexo to name the basics), Video...

So you want to learn a varied range in vector, pixel, 3D/Cad and animation software packages.
