Hi Pixiebell,
Yes, you definitely have the right idea. A review site is a great way to start. I know several people that have very successful review sites using affiliate marketing - vacuum cleaners, juicers, etc.
I wouldn't use other people's reviews on your sites unless you just read their reviews and then put them in your own words. Unique content has more value and you don't want to be in danger of breeching copywrite.
I think you'll do much better building your own site rather than paying some web designer to do it for you. It will have your own personal voice to it and you'll know it is done the way you want. It doesn't have to be hard if you have the right tools and guidance.
The number 1 product I recommend to anyone and everyone is Sitesell's
SiteBuildIt (SBI).
The reason I say SBI is because I have used it personally and know from personal experience how great it is for producing a quality site that gets free targeted traffic from the search engines.
The SBI package includes your domain, hosting, step by step Action Guide (written and video), brainstorming tools, simple blockbuilder (for those of us who don't know beans about html and coding), analyzing tools (to be sure your pages are search engine friendly/SEO), autoresponders, automatic blogging, a very helpful forum and much more.
Once I joined SBI I didn't have to purchase anything else. It's a one stop shop, if you know what I mean. Sure, I could probably get a bit more advanced and add some things that aren't specifically part of the SBI basic package. Maybe one day I will. But it isn't necessary to success.
I actually feel sorry for people who don't have SBI. That may sound silly, but it's the truth. I know how much easier they have made my IM life and I think it's a real shame when others flounder around without them.
I hope your upcoming review site is a smashing success!
Blessings,
Angie
