Call Shops to check if they’re selling cameras

I’m looking for someone to make a round of phone calls to the 197 shops in my spreadsheet and ask whether they have cameras for sale. I’ll share the spreadsheet privately with the assigned Tasker. Please make the calls over two consecutive weekdays, Monday to Friday: about 100 on the first day and the remaining 97 on the next. Start at 10:00 am Perth time (GMT+8) and aim to call each shop within its first one to two hours after opening. If the first round goes well, I’d like to repeat the calls every fortnight.
