To be honest, I'd take the time to find a trusted provider here on Sythe that fits in with a price that you see is feasible.
2 great providers have already been mentioned in this thread. There are other big/reliable providers like Tweeter and there are also smaller providers that I can only assume have a fair few capes under their belts.
One big reason I suggest getting it done by a trusted provider here - even if it costs more - is accountability. Regular providers here know the value of your satisfied business - because dissatisfied customers will directly impact them. Using an unknown website does not have the same effect - proven by you needing to come onto Sythe to ask about them!
TL;DR Even if it costs more, I'd use a trusted provider here.
