For further possibilities, if you see a member claiming to cast for you and asking money for such, please do warn a moderator.
If you see them also posting e-mails, phone numbers, addresses, also warn a moderator, if you please.
Never trust such members, has HearthWitch stated it's more than likely to be a scam.
Regarding the spell cast, as long as it is achievable, the spell should work. White can be a substitute for any other candle color, which is nice. Regarding brown it's more Earthy. So balance, stability, house workings, grounding, over coming situations, etc.
