Costs:
1. Do plenty of research, interview local landscaping businesses, ask them for help in your project - how they started, what inspired them, how much it cost..
2. Research costs of equipment
3. Research tax payments for a self-started business, and also salary requirements (ie minimum wage for expected staff, and of course yourself)
4. go to all the banks, make appointments with the business advisors, ask them for any financial forecasts they could provide. Take all your research with you, it will show you’re serious and aren’t wasting their time - they will take you more seriously then
Competition
1. Check the current market - all companies offering a similar service in your area. Don’t forget to take into account people who would do it themselves
2. Make a questionnaire, and go out and ask a sample of 100 people what they’d do when it comes to landscaping. This is a great resource, you can also use this to gather how much people are willing to spend, the area of their land, and perhaps a checklist question of what services they’d require and the frequency of it (ie they want a water fountain installed and then upkeep monthly)
Problems:
Again, contact existing companies. Interview them, make sure you prepare so you can get the most out of your time, and video/sound record it, so you have a transcript for your project.
It may be a good idea to get in touch with a compnay that hasn’t succeeded in business (closed/ been bought out). It’s good to research why it won’t succeed as well as why it can. You can then take the negatives into consideration when you write your conclusion.
All the best of luck with your project!
