Consider selling in lots. A lot is a collection of similar items that is sold in a group. For example, if you have a collection of books, magazines or similar pieces of jewelry, consider selling them all at once in a lot. You many not make as much money as you would have if you sold each item separately. However, the items will likely sell more quickly in a lot than they would individually.
the problem with “CashCrate” is that the amount of money that u get out of it is VERY slim.. and even to get that VERY slim portion of money you have to complete a lot of surveys and to cash-in on the money you earned u must make over $20, trust me. i tried it, it took me over 6-12 months to get the cash.. i used the site like if my life depended on it. it was very hard.

Perhaps the coolest thing about the Amazon Associates program is that you receive credit for any sale associated with your affiliate link for 24 hours. So, if a customer visits the page of the product you recommended, but then goes on to purchase five more eligible items during that same visit, you will receive a portion of that entire sale.
When I used to write product reviews, I used to include just one affiliate link. For some reason, I thought that a single link would be enough and I didn’t want to run the risk of annoying readers with more links. However, one day it struck me that the reviews I was writing were quite long and by the time people got to the end of them, the link to Amazon was no longer visible.
In corporate law and taxes, an affiliate is a company that is related to another company, usually by being in the position of a member or a subordinate role.

Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Research other listings in your city on AirBnB and see what the going rate is for a place like yours. You could also just rent out a private room as well or even a bed in a shared room. In fact, that's how AirBnB got its start. However, you might find it hard in the beginning without reviews, but as long as you take really good care of your guests and provide a lot of value, the reviews will eventually come rolling in.
