Is This A Good Adsense Action Plan?

Hello. I currently have a full-time online music business selling my hip-hop, pop, r&b, dance etc. beats. I've had the business since 2008. As the business grew, it provided me with a nice 6 figure yearly income, but the past year it has taken a huge fall and it is slowly fading.

Because of this, I have decided to start an Adsense campaign to supplement myself with some more income, and to generate another stream of income for myself to compensate for the fall of my music business.

I recently came across a free Adsense course that some of you may have heard of called "Make Money From Homr Lions Club". I found it to be a wonderful, consise course with huge emphasis on keyword research and all of the necessary steps to build 10 Adsense websites to eventually earn thousands per month as the sites age and gain authority.

The course is free and seems very honest, but it does have a lot of upsells and affiliate products linked to it, which leaves me a bit skeptical.

Anyway, I do have a bit of experience in Adsense, as I built a few MFA sites back when they were popular. One site was making me around $22 per day with 5 pages of content, but quickly fell off because of the black hat methods I used.

So, I have decided to give Adsense another go, but this time following the Lions Club guide which is based on quality content and white hat methods.

I am just interested in some feedback as to if my plan seems like it could work. I welcome any advice, comments, criticisms, etc. Here is the plan:

1. Create 10 websites using Wordpress, each one about a different niche

2. Use Market Samurai to find at least 10 keywords for each site that I will be able to rank #1 for, based on pagerank of the competing websites for each keyword

3. Write an article for each of these keywords, utilizing additional related keywords in each article to bring in some extra traffic

4. Do the necessary link building (outsourcing articles for backlinks, contacting similar websites for link exchanges, etc.)

5. Continue building the sites that are performing the best, and focus on those

I have about $2500 of expendible income for outsourcing. Is this Adsense action plan worth investing in? I will do all of the keyword research myself, write some of the site content articles myself, and outsource the lower-tier articles for link building, etc.

With the proper keyword research, 10 quality sites with at least 10 posts each, backlinking and over time, is it possible to pull in about $1000 per month total from all of these sites combined?

I am just a bit hesitant to begin, because I do not know the current situation with Googles algorithms, and I fear that some methods may not work anymore.

Also, can anyone reccommend a good site for buying quality articles? I am willing to pay $20-$25 or so for a 500-700 word expert-level article, and maybe $7 or so for an article for backlinking purposes.

Thanks for any info!
