suggest how to fix this scuff on bumper?

i've had this on my bumper for over a year now, but want to do something about it. i've thought about taking it to a shop, but i'm wondering how much they might charge for something like this?
i have no paint/body experience, but i do have some stuff i picked up from paintscratch.com (basecoat pen, sheets of 220/600/1000 grit sand paper, and i think some kind of clearcoat).
i could take a better picture - this one was taken in the rain.
it doesn't look like the scuffs go too deep, but they can't be rubbed off. i think a 90's dodge minivan nudged me.
what would you guys do?
hugger-96-lt1, thanks for the suggestion. it is way above my level of experience, though. should i just take it to a shop? how much might they charge me?
i picked up quixx scratch remover which is basically 3000 grit sand paper and two tubes full of some liquid ("polish" and "finish").
i wet sanded the spot for a bit. 3000 grit didn't seem like enough at some parts, but i just kept it clean and used a little more pressure. i still need to take a good look at it in different light conditions to see how it is, but so far it looks pretty good.
before...

after.


it feels pretty smooth, but that could be the finish compound. i'm not sure how much damage you can do wet sanding with 3000 grit, but is it possible that i removed enough clear coat to cause eventual clear coat failure?
i remember hearing somewhere that there was a spray-on clear coat somewhere that would blend in with the existing factory clear coat, but i cant remember what it was called. any suggestions?

Looks good though! My girlfriends bumper had what we thought was a deep scratch with paint rubs on it. I buffed it out just to make it stand out less and it took the whole thing out. Sometimes you get a pleasant surprise, othertimes you find more work for yourself..

if i did burn through it, how long do you think it would take before clear coat failure?
should i just keep the bumper waxed? if i did burn through, i'm thinking the factory basecoat wouldn't last too long. that bumper is going to see a lot of sun. should i just apply wax every month?
Thanks!
