New Online Blogging plan that Focuses on helping more than conversions first

Although I am not new to this game, I want to do it right abd plant the seeds of my niche efforts overtime and i was wondering if this strategy can work or what need to Tweak down the line:

Buy a Professional WordPress Theme focusing on Computers and Tech Gadgets(my Niche which im good at). Fiverr can help greatly with this for a decent price
Buy Hosting for ONE domain and focus work efforts on an authoritative site directly to that
Utilize keyword research on you own or freelance the job for a much easier time
Reuse bought AND own written content for use once more (Your prospects want content that helps them MORE than an upsell)
Utilize Affordable Content Writing Services
Use Canvas to solve the problem of images for the blog(my biggest peeve since trying to get images for my blogs).
Use Pinterest and 2nd being Facebook(only 2 social platforms at a time to avoid burnout) to promote said Canvas creations to drive traffic killing 2 birds with one stone
Use Email autoresponders ONLY after you see a decent amount of traffic coming towards the site
After this is all done THEN sign-up for affiliate programs.
Prioritize on gaining trust by helping prospects first and foremost before anything else and monitor traffic accordingly.

Any help Is greatly appreciated if i am wrong about this.
