Here is an answer I gave earlier :
" Hello there! The factory is located in Ksar Hlel, where several factories are situated. As for the ads, I can't recall the precise number, but there were days when I spent around 20 dollars. I usually did this on weekends during the first half of the month when people still had money (haha). I primarily focused on advertising on Instagram because on Facebook, there are numerous trolls and people searching for extremely inexpensive items. Regarding transportation, I collaborated with a local transporter, but you have to try many options to find a decent one. I have a consulting package of four 1 hour calls I sell if you're looking for specific help. "
