What do you do when you are handed over a 10,000sqft empty shop on one of the busiest roads in town, when you have very little capital or not much ideas on what to invest?? any ideas???

Simple. You tell the person who handed it to you he/she handed it to the wrong person!

Hata "kukatakata" ziwe stalls ni kazi? Na uitishe wakenya "good will" - never mind you are not selling a going concern! Wakenya wanalipa tu - na six months rent in advance! hi ni swali gani huyu jamaa anauliza????

make a flea market. Kind of like before stalls were partitioned. Each trader only needs to come with his own table and sell his wares without partitions. Simple.
No capital required.
Kazi ni kuka hapo kwa entrance na stool na kitabu hard cover ya ku record rental income. Period.

Rent Out or you also give out like you were given

fuga ngombe na kuku na nguruwe huko !
