"As for the things I need to do for the building of the travel agency, there are several aspects. Firstly, I will make a checklist which may involve how much money I should have to start the travel agency, and how many people I should employ to promote the business. Secondly, I also need to apply and get certain qualifications, like the business certification and health certification. It may be illegal to start the business without any permission from the government." Your short essay here is relatively good, just a few corrections. I recommend you to put it up in the Notes section of the italki website so you can get more people to check it. I put my Japanese essays on there for people to read and to correct as well, so highly recommended.
