“want to start a business process of starting your own business”

This is a great time for a concierge business or errand business startup. In many areas where there is significant development in the luxury market (residential and commercial), you will find increasing opportunity for concierge service providers. I remember my first job as a residential concierge, which helped me start a concierge business from home. The knowledge I acquired while employed by an established concierge business set the groundwork for my long-term career as a concierge business entrepreneur and author.
Over the last decade, high-speed internet, a proliferation of devices and applications, and changing attitudes about the nature of proven private label have made working at home a reality for millions of people around the world. One study, in fact, concluded that nearly half of all American employees work at home. And the trend isn’t limited to the United States; 79 percent of knowledge workers globally now do at least some work outside the office.
Who are your competitors? Do a competitive analysis to identify key competitors. Find out who is doing something similar to what you are planning, and how have they been successful. Just as important is to find the failures, and what made their venture fall apart.
It’s amazing how many people have a computer and still don’t know how to make flyers, presentation decks and other visual assets for their business. If you’ve got a good design sense, are familiar with your word processor and already have a laser or high-quality inkjet printer, you can get into desktop publishing. Create a really great-looking portfolio for yourself and go door-to-door.
Recognize that getting your business off the ground will take time. Most businesses don’t become profitable right away, so plan for that in your personal life too. You will be making sacrifices to be your own boss.
If that isn’t enough, you can expand your services to include pet grooming as an extra side business idea. To do that, you’ll need to have relevant training, an operating license depending on your location, and pet grooming equipment. According to PayScale, pet groomers have an average salary range of $17,600 to $48,500. Not bad as a side business  idea if you can find a way to get in most of your clients on the weekends.
I think a window cleaning business is an ideal way for someone to start their own business because of REPEAT customers. All you need is one large account (nothing too high) and maybe a dozen small storefront customers to make a possible $200 a day.
You will need to think about your location, equipment, and overall setup, and make sure your business location works for the type of business you will be doing. You will also need to consider if it makes more sense to buy or lease your commercial space.
