How Much You Can Actually Earn?

The fun you can get out of the job is already rewarding enough; how much more when you are actually paid not just by regular rate but by commission as well. You can actually charge as high as $8 for every order and get a 15 percent commission for every service. If you are keeping this as a sideline, you can actually pocket a whopping $20,000 annually.

And How Much Do You Exactly Spend?

There isn't a lot. You just have to be determined with your marketing abilities. If you are not attached to any personal shopping company, you can start printing out flyers and posters which you can post all over your neighborhood. Everything else will just be based on the word of mouth.
