Hello and good day. Looking to get started in Affiliate Marketing

I'm a complete newbie to internet marketing and Affiliate marketing. Fear not!! lol... I'm not here to ask stupid or annoying questions. I have been spending a considerable amount of time researching affiliate marketing and the basics of it. Of course no one who ever starts gets in the business to be broke and do it the dumb way. This is pretty much the step by step idea I have in my head about how to go through with this. I am writing this step by step list to purposely get guidance on what to do correctly

1. Find a niche

So I believe I already have a niche: Cellphones and Cellphone repair.
This one is something I'm familiar with as I do have plenty experience fixing iPhones
Its tricky though. I'm debating within myself if I should just find another niche or just continue to drill down on this one. I have already started a WordPress website for this niche back when I thought I would be doing 100 repairs a day. I'm guessing already familiar with it I should just stick with that to start rather than looking into another niche like weight loss or mediation or make money online products. I don't know if there are any good affiliate products related to the niche of cellphone repair or DIY Cell phone repair

2. Conduct a keyword research to help drill down the niche I already have or find a new niche

So as it turns out I know absolutely nothing about keyword research. I'm looking to get guidance here on that as well. From what I do understand there is a way to come up with a set of keywords that are low competition but highly profitable. I don't know how true this is.
The keyword(s) must have at least 800 searches per month. Please feel free to correct me if I am wrong about this. I want to generate a list of at least 100 keywords. I want to make the keywords short tail keywords as well.

3. Head on over to ClickBank to Find a product based on the keywords you have amassed.

I guess now after you have your keywords you can pick a product that closely aligns with the keywords you have selected. Ideally I think I would want to go for a product that has gravity of 20+, 50% + commission, an attractive sales page ..... etc

4. Write a convincing sales copy for your landing page that helps me stand out

I don't know anything about this because I am not a marketer and I don't consider myself a good salesman. I guess I would have to have someone guide me on that.

5. Get a landing page with and auto-responder and list building software for your product
I don't have any webdesign skills so I don't know how I'm going to this. I've only heard of one list builder and that is ClickFunnel I believe. I believe ClickFunnel is supposed to help me convert traffic into an email list or something like that because I read somewhere generating traffic with no list builder is practically pointless because you won't be able to optimize your list to drive sales.

6. Last but not least Generate traffic through SEO, Paid ads and Free organic serach rankings to the sales page to convert the lead and make the money.

I don't know anything about SEO either. All I know of is keyword research. I guess I would have to skim through any articles on this website to find valuable information on SEO and other ways and strategies to generate traffic to my page for free since money is kind of tough right now to spend on an ad budget (Facebook or otherwise)

What I'm looking for since I'm a complete dummy is a step by step plan on how to get everything done. Like Tony Robbins said "Complexity is the enemy of execution". I think the reason why a lot of people like myself hardly get anything done is because of the information overload and how complex and complicated it all seems. Hopefully you all can help with that.
Thank you all for your help in advanced. Good day and be blessed.
