Affiliate Marketing Secrets

Do they charge a monhtly fee?

I am a full time employee. As a hobby I’ve started creating web pages on free platforms (free hosting and free sub-domain); those pages also include affiliate links from Amazon or eBay. Let’s say I will, at some point, make £20 per year. Do I have to declare myself self employed, start filling in self assessment forms and pay tax to Inland Revenue for £20 of additional earnings (on top of my annual salary)?
If not, being a negligible amount, then what is the threshold (if any) above which you have to declare yourself self-employed and start paying taxes? If there is no exact threshold, does this mean that the Inland Revenue is expecting getting taxes from (let’s say) a person that makes online a £1 profit (paid into his bank account) from selling one item on eBay?
Thank you.

I’m thinking about creating a movie database site similar to IMDb. However, I need to know if I need to gain permissions from movie studios to use the movie synopsis/description, cover/poster image, etc. of the movies on the site? Or, would that be covered by the fair use law? Will I need to right my own movie descriptions of each film?
Also, I would like to be able to make money for promoting the movies at some point (if I can right off the cuff, then great). You know, by signing up with Amazon and Netflix affiliate programs. So, what’s the best way to do all of this without getting sued (since everything in the world seems to be copyrighted material)?
Thanks.

I have a really good niche. I am a researcher, and I build these blogs naturally. My main blog site has been up about 10 years so I have a good following, but not enough blogs. I have around 200 blogs with adsense and amazon on them. I am making only about $100 dollars a month. So I need around 6000 blogs in order to benefit monthly. I would like to put up about 20 blogs per day. Is this the right thing to do? I don’t use bots or autoblogs. I place all of the ads on my site naturally.
