The only costs associated with a good website are your domain (about $10/year through NameCheap), hosting (SiteGround, even A2 if you want really cheap…about $5/month or less), and a WordPress theme (there are some good free ones but most of the big guys use StudioPress which is a $100 one-time cost). WordPress.org is free and can be installed in your hosting account.
Regarding “convincing someone to buy your product is not that easy”, I do agree with you, but at the same time, I remember all those products I’ve bought online. I did not search on Google for those products neither I went to the company websites to get information and buy. They were affiliate people and their blogs that inspired to buy them. PrettyLink Pro, SEO Pressor was recommended by Kimberley, I bought Profits Theme, WP Zon builder because Alex Whaley recommended. Similarly I bought CommentLuv Premium because Ileane, Kavita, Steve and many others were talking good about it.
Mechanical Turk: Amazon's Mechanical Turk is a resource for doing human-intelligence tasks, or as the site commonly refers to them, HITs. You get paid a very small fee for any given HIT and you'll need a good deal of volume to make a substantial amount of money. But it is a resource you can use in your spare time to generate a small income online.
To be honest, I know nothing about the EU or the UK. as an affiliate you are simply an independent contractor, here in the United States we get a tax form called a 1099 that reports our earnings and we have to self report all earnings and pay taxes on our own. I usually expect 30% to 40% of my income will be taxed and that is a conservative estimate so I don't underestimate. Best to find someone more familiar with Europe, the UK and your specific position to give you specific guidance… With that said remember, the only time you deal with taxes is if you're making money. If you don't have a website built, you don't have an audience growing, you don't have dozens if not hundreds of posts published… You are very far away from earning money and a thought about a future challenge that is not real yet is holding you back from getting started. The most important thing to do is to start
When promoting a product, you are also promoting the person or organization that owns the product. This should be the first thing to know before selecting the product you are promoting. You surely don’t want your clients to be unhappy after purchasing the product. Trust me; they will never come back to your site again to purchase anything! This is because you have dented your credibility. Normally, any company or website with good customer service is bound to have happy customers.
Transcription is one of my part time jobs. I can do it conveniently from home and many of the clients are trainers or speakers. Having money and needing transcription services doesn’t imply you have a secretary. At my full time job the closest we have to a secretary is the CEO’s assistant. She books flights, plans travel, schedules meetings, transports his children, and helps with home renovations. She doesn’t have the time to sit and transcribe work when the CEO can send it to a company or freelance agent for a few dollars.
