I just read your hub and you are doing fine. Amazon will not be a big deal for awhile so enjoy writing and forget about the cash. In a few weeks when you have 25 readers a day or so apply again. I have made very little from Amazon and then one day I wrote a hub about hanging pictures using alternatives to a nail in the wall and someone bought several art hanging rails with about a $50. commission. then back to almost nothing.
To get a readership going, comment on other peoples hubs to get some exposure, follow others here and if they like your work they may follow back, post on twitter, instagram and other sites. Keep writing and you will see some results. If you hit on a topic everyone reads and it is a special niche you may see lots of traffic from just one or two hubs but it will be hit and miss,
