Fixing errors in design of our local airport FS02

[mojavepilot]

I would like to fix the errors in the layout of the airport where I am currently earning my pilot license.  The airport is KEHR.  There are 5 hangars you can rent spaces in, 1 privately owned (by our family owned company where we keep our Mojave), and 2 owned by Don Davis Aviation that runs the airport.  I would like to add these buildings as weel as change the textures of them.  I would also like to put a few planes on the ramp and a fuel truck.  The office building is currently under construction as well as the runway when this is finished I'd like to edit those too.  Can anyone tell me what I need to do this and how to do it.  

                                        Thanks,

The easiest utility for what you want to do [in FS2002??] is FSSC, in my opinion. There are other utilities which I have never used. FSSC seems to have the easiest learning curve.

The easiest FS9 utility for what you want to do is Rwy12, in my opinion.

Sorry for the response delay.  I had given up on anyone responding.  I have FS2002.  To my understanding FS9 is the same as FS2004 right?  So I'll try the FSSC.  If I'm mistaken and don't like FSSC then I'll try Rwy 12.  Thanks for the replies.
