custom soundboard/led driver board for lightsaber

Yes I'm planning on making my own custom led driver/ sound board for my son's and daughter's lightsabers that Im starting to build. The led driver needs to have a extension/ retraction (scrolling) effect for the led 8 string/channel blade on power up and down with fade in/out for each led segment/channel in sequence. A static shimmer / flicker or candle effect, a flash on clash effect. These need to be synced with the soundboard that can be programable with a power up/ down sound font, an idle hum sound font,3-4 random swing effects sound font triggered by a swing/ motion sensor( for up down and side to side swings), and 3-4 random clash effect sound fonts triggered by the clash/ vibration sensor. as well as 1-2 accent led pads. and have a micro sd card slot for loading/saving other sound fonts. I plan on using 4AA batteries at 6 v or a lith ion recharge pack at 7.4v. Im not use to this kind of electronics and only have use of one hand so I need some help/ direction/ comissioned builder and need to know what exactly I need to do to get this made. Please help Thanks
