Gonna sound a hard barsteward here, but that's a pretty poor excuse all those models can be sold on eBay leaving you loads of time to canvass
The father in law was like you, spend loads on all the kit, then the excuses started as to why he couldn't go out getting customers, oh I just need a so n so, oh booked a holiday, oh weathers a bit poor, oh, need a different leaflet. And so on...
8 months later he barely had a dozen customers....
You need to be committed ( yes like me to the looney bin ) otherwise you will drift and fail, but best of luck
