It's worth considering that the reason you have to spend so much time and resources on SEO and getting on Google's first page is because there are so many hundreds or more people doing exactly the same as what we're doing. And most of those are playing exactly the same games with SEO and Google-rankings so that they get ahead of you on the first page.
You have to ask yourself the question of - why would someone chose you over the hundreds of alternatives?
I don't want to sound like a doom merchant, but it costs so little to start up now that everyone thinks a couple of hundred quid on equipment and they'll suddenly be making shedloads of profit overnight. Maybe that'll happen, but you'll be one of the few if it does.
Just be realistic with your expectations.
