Startup Idea : Farm Manager App

Actually now a days there is alot of problem getting the people for working in the farming fields.. in future the Agriculture will be the main occupation.. and in some of the areas there is alot of people were there and they are ready to go any jobs.. my idea is we need to work as a bridge between them.. we will ask the land owners to say how many people were required for them that day.. and we will ask the people who were ready to work in agricultural land to sign up a contract with us .. and we will provide the people to the land owner to work for the day and we will get paid from both the sides as small amount of money.. we will develop Android App for this .. just they can directly interact with the workers directly through our App...
