You do not need to have 'high net value', and yes, you can invest in it.
Typically, fund companies require a minimum investment, that could be 100, it could be a 1000. 5000 should be enough for 99.9 % of all funds for an initial investment.
What you need is an investment company that manages the account for you. I cannot name those for your country, but they should be easy to find (companies like IMG, and Fidelity might serve your country). You then open an account with the company of your choice, transfer the money, and tell them which fund it shall go in; all this is possible online.
You can also go to see an agent in person, and he will fill the forms for you, and handle all the action, but he might take a fee for it.
