Best tools for gardening business?

Hi,
For a little while now I have been doing grass cutting and tidying for a few people as a bit of pocket money. I enjoy it, and have been using a borrowed lawn mower and tools. I recently lost my job and am looking at doing this full time. I am wanting to buy my own equipment, but I don't want to go out and buy something that will fall apart for fail to start after a few weeks. In terms of mowers, what should I look for? I aim to do residential properties so, in terms of blade size what would you recommend? I am a
tempted by a Honda petrol mower as I believe these would probably be one of the most reliable? This particular one has a 46cm blade. I am having business cards made up and am buying some PPE and decent clothing. I think that's wise plus I think it looks a little more professional. Any advice would be great fully received
