I agree with the other posters above. Because MarketForce is self-assign and their guidelines are very good, their shops are usually simple, the reports are short, and they require almost no writing skills, I would say MarketForce is a good training ground for new shoppers.
BUT - - - a new shopper should keep in mind:
You will only get paid if you do the shop according to the guidelines. You don't get paid for showing up and trying.
Follow the guidelines completely. If the guidelines require a purchase, you MUST make a purchase. It doesn't matter if you can't find anything inexpensive that you like. If the guidelines require you to order a specific item, you MUST order that item. It doesn't matter whether you like the item or not. If the guidelines say you must time service, then be sure you have a stopwatch and you can time the service. Not providing service times because you didn't have a watch with a second hand is not acceptable. Many times new shoppers post here devastated to learn they will not be paid because they didn't think something was important or necessary. One new shopper complained that he had taken a shop that required a purchase, but he couldn't find anything inexpensive to purchase, so he completed the shop without a purchase and submitted the report. He was shocked and angry that his shop was declined.
Check to be sure the location is open and double-check the address. You can usually Google the client location and see exactly where it is and its hours.
Be prepared to react quickly and to improvise. Sometimes shops don't go as planned. Murphy's law. Anything that can go wrong..........
Be prepared to be nervous during the first few shops. Just be careful and detailed and follow the directions to the letter.
Good luck. Have fun. Make lots of money.
