meh if you think you ahve the guts for it do it, i did this to my brothers micra when i was 15 my first attampt at spraying took about a week to do but i think i did i good job to be ohnest ( he hit the wall on hour drive ) no pictures of before i sanded it down tho ) But it was a hard one because i had to blend it in oh and i used rattle cans, and i found that using tinnies from my local motor factors where better quality than halfrauds rattlers
Sanded down damaged area

Removed dent sanded, then primed

Sanded them primed

Then this is the final result 1 can of primer 1 can of paint and about half a can of clear in total

Not got a pic of the car fully put back together lights ect or washed and polished
Hope its inspried you to do some of your own maty, it was all masked off and sprayed in my garage
