Don't make a custom mods folder inside Gamedata. Most or all of your mods will not work. It has to be Gamedata/WarpPlugin and Gamedata/Squad and Gamedata/NASAmission and Gamedata/TreeLoader and so on or things will not work. Do not nest mods in other folders.
Stop using this. Use the updated Extraplanetary Launchpads. Orbital Construction is made for an earlier version of KSP that is no longer supported and mods in general are largely version dependent. Just stop.
Zero problems with Toolbar and Alarm Clock here. Are you sure you don't have multiple copies of either mod buried in some other mod folder? Different versions perhaps? Are you trying to use the modded 64bit KSP which does not work with all sorts of mods?
That's one way to do it. Or you could have sent up enough and timed things just right to make geostationary's. Or you could have sent up manned missions to place geostationary's or some similar orbit high enough to provide coverage with fewer satellites.
