@IzzyAg, First off, you need to define the quality of coffee that you are looking for, (Better than the railway station is pretty broad brush). Taste and quality of coffee differs from person to person. You also need to identify exactly how much work you wish to put into making the coffee, and the amount of work you wish to spend keeping the apparatus in top condition, as this effects both taste of coffee and the reliability of the equipment.
I suggest you start off by visiting a number of establishments that make their coffee in different ways (eg, drip filter, expresso etc) and taste their output, have a chat with them on what equipment they use and how much work is involved in both coffee prep and equipment maintenance.
From this you can then decide on your method of brewing and look at equipment to match.
As previously stated by others, with far more knowledge than myself you can then decide if you wish to grind your own beans for your particular method of brewing or buy reground from either a local roaster or wholesale distributor.
Most home brewing products are not suitable for a commercial environment, yes some may cope initially, but their longevity may well be compromised, and you’ll end up spending more in the long run. (Read my Avatar)
