With this being in mind i would like to review *PRODUCT NAME* If that would be possible in return i can offer a stellar review with promotion to *PRODUCT*
You should NEVER offer a 'stellar' review in return for a product, you basically lose all credibility by offering to be positive in return for something. An honest, or in-depth review would be a far better offer than 'stellar' otherwise it just looks like you're saying "Hey, give me free stuff and I'll give you a great review."
What happens if the item turns out to be garbage? You're then duty bound to say the opposite and that does no one any favours, least of all consumers who might be tempted to spend their money on the product of the back of your recommendation.
Another thing that hasn't been touched on in this thread is PR (Public Relations) companies that often take the job of finding the best outlets for publicity - it's not always the manufacturer or distributor that handles the PR requests.
If you can find out who handles PR for a particular company whose products you want to review, the first stage would be to ask to be put on their mailing list for press releases. Provide coverage off the back of those for a while without asking for anything else, each time sending the coverage links back to the PR. Develop a relationship with them. At some point they may flat out offer you a product to review, or if something comes up that takes your fancy - after you've developed a relationship - you can ask about the possibility of a review unit with much more confidence.
I've had a literal ton of free stuf over the years that's been reviewied through my site; DVDs, Blu-rays, t-shirts, posters, event tickets, press passes, preview screenings etc. and it's all come from staying professional and developing relationships with the people and companies that handle publicity.
Good luck!
