That's an excellent eevee. Evolve asap.
It's a Flareon, not an Eevee

I wouldn't bother tbh, you'll be able to find Eevees at that CP low-mid 20s or something. Getting a good Eevee isn't actually that hard since the Attack IV is tied to Pokedex number, so Eevees, Magikarps etc pretty much all have 14/15 attack (and the opposite is true with starters, you generally want to find one in an egg to evolve), this means you only need good rolls on Stam/Def which is much easier

1 out of 57 Eevees should be at least 15/13/13 if you assume that Eevee can only roll 14+ attack (which is pretty much true afaik).
Also remember that IVs only matter if you're going to keep them max leveled since CP is just a single number representing the combined Att/Def/Sta, so if you aren't actually maxing the pokemon out having better IVs isn't better than having high CP.
Obviously you can keep the pokemon, but I wouldn't spend anything on it until much later if you ever do since it's pretty likely you'll find better (or close enough and much cheaper)

Edit: Also, don't forget to see how good it's moves are, bad moves can make much more of a difference to damage (in general, I'm sure there's some that are all pretty close) than IVs, generally IVs only make up around 10% of a pokemons actual stats or something.
For example Flareons base stats are 238/138/130 (IVs are added on top of this) even compared to a 0/0/0 a perfect Flareon isn't massively better when compared to the upto 30% difference a bad moveset can do.
Edit 2: Flareons moves are all fairly close actually (similar to the difference between 0% and 100% IVs) their relative damage is Fire Blast 100% Offence 90% Defence, Flamethrower 93% Offence 100% Defence, Heat Wave 92% Offence 82% Defence.
