Great video by Curtis Stone about his take on what the three hardest issues for running a small urban farm. These are some of the same issues I have been harping about for several years. I believe that they are not particular to any small business by you will find they are common for most of us choosing the entrepreneurial path.
1. Marketing your small business
Spend 50% of your working day implementing your marketing strategy. You can out-source this but it is expensive for start-ups that are cash strapped. I recommend Dan Thies for long term sustainable solutions https://twitter.com/danthies?lang=en
2. Accounting for your small business.
Hire a book-keeper.
3. Staffing your small business.
Use a payroll service.
