* Don't worry too much about crazy contracts / terms of service. If you run a business you will end up signing all kinds of ridiculous contracts. If you are worried about the consequences, get a normal job instead.
* Don't expand to other markets before you've managed to crack one market. Right now you can experiment easily with the site, if you expand to many countries making changes will get a lot harder.
* Who are your customers? Who is using your website? This is the most important question, and further development of your website should start from here. Are you targeting hard core gamers who want to get the highest frame rate for a budget? Or are you targeting parents who want to find out how much they have to spend on a PC that runs Minecraft for their kids?
* What are you doing to promote your website? How do people find out about your website? I see you have this bbcode widget, so I assume you are hoping that forum users use your site to share configurations. Are you doing anything so people can share configurations on Facebook / WhatsApp / whatever people use to communicate today?
