Shop Script Help And GUI Help

[RicoTheNinja 10]

Hello there I am new to this Scripting idea but seem to have made a breakthrough with an idea. I am running around 6gb of mods and am looking into adding stores to those items. I am using a modified by me version of BIS's gunstore script, is there any better way to acomplish this feat via array as the BIS system is a .sqs script per gun and I want to cut down on this.

Also can anyone point me in the direction on how to setup a GUI like in takistan life for shops

And a vehicle shop style script

And how to add shop functions to gun boxes like in takistan life.

Thanks for any help
