well, i replaced the whole front bumper on my 2010 corolla (and obviously painted it)... i didn't use OEM stuff, but looked pretty damn good to me. i had 3m on my hood and fenders, so the blending was unnecessary...
total cost was about 450 including taxes iirc. this was on the one i sold to AP.... he seemed happy with it and it is going strong almost a year later. but i did get an amazing deal on it due to the amount of business i do with that shop.
overall, the price seems fair... but with that being said, i'm sure you can do it for less.
