There are many ways to raise capital. Some of these are listed below.
Not all of the items in the list below will apply to you.
Savings
A good source of money as you are not paying interest.
Bank Loans
May be a good choice but you will need to look carefully at the interest rate.
Loan from Family/Friends
A loan from family or friends is often a good solution but could this put personal relationships under strain?
Grant
A good way to assist your Business. You need to find out if you meet the criteria. Your local Chamber of Commerce and/or regional Business Support Agency should be able to advise on availability and eligibility.
Investor/Partner
This may provide a source of income. However, they will want a share of the Business in return for their money.
Part time employment elsewhere
This may provide a good solution, although it will mean that you have limited time to invest in the Business.
