Getting a "flawless" look depends on what skin issues you have to contend with (if any).
If you have normal, even skin with few imperfections that a light to medium coverage foundation will do the trick. If you have more to contend with then you may need a more full coverage.
Also, achieving a flawless look may require color correction in some cases. If you have a lot of redness, sallow skin, brown spots etc. then a color correcting primer may be the key to a more flawless look.
Also, don't forget to choose a foundation depending on your skintype. This is most important when choosing pretty much any base product for your face (foundation, concealer, powder even cream blush)
A final note, adding highlighter on key places on your face (tops of cheekbones, browbone, cupid's bow) helps to add that radiant effect that contributes to a flawless finish.

I would have to agree with the other ladies who have posted on here who have said that we need to know more about your skin type and needs in order to give a better recommendations. However here are some of my favorites:
- Makeup Forever HD Foundation or Matte Velvet + if you have oily skin
- Lancom's Teint Miracle - very buildable if you dont need a ton of coverage
If you have specific issues/needs with your skin then you can repost and we will give suggestions that are better tailored to what you need.
I agree with islandqt -- to be honest, a flawless complexion depends on your skin type, which you didn't mention -- so if you could update your post re: your skin type and any issues, it would be helpful in determining the best foundation / concealer for you.
You just have to know how to blend. Blend. blend. blend...haha. I can get a flawless looks with my ten dollar liquid foundation as well as with my 60 dollar liquid foundation. Anywho, a really good one that will help you if you haven't got the hang of blending yet is either Makeup Forever's Hd foundation or Laura Mercier's Silk Creme Foundation. The silk creme is high coverage and might disrupt oily skin, so make your decision off of that. Both are good, and blend in better than your average.
An excellent full coverage foundation for normal or combination skin is Laura Mercier Silk Creme Foundation. To get a flawless look, you also need a finishing powder (MUFE HD or Laura Mercier are excellent) and a good primer that should address whatever issues you have, like redness or oiliness. How you apply the products really makes a difference, too. I've learned a lot from the makeup artists at the Sephora store in Philadelphia.
I know this isn't sold at Sephora, but try M.A.C's Studio Finish Foundation. It is a thick foundation with maximum coverage and gives you a super flawless look and it's only about thirty bucks.
