As narcist has pointed out that is I guess, a way you could take the story of the rich young man, however, Jesus told him to discard his possessions as they were becoming a barrier between him, and God, and was hindering their relationship.
If we are using that money (So maybe a worship budget) for the honour of God, and to develop ours, and others relationships with him, then it is allowed.
But then you need to make sure you don't go over the top. Down South there's a church a friend of mine went to once, called Christchurch Bristol, and as much as they put their heart, and soul into worship, having a full set pf brass, strings, and all sorts, as well as the ususal Guitar, Bass, Keyboards and Drums, is a bit mad Ted. If you're spending more time orchestrating, and working on the music than the worship you need to rethink what's going on.
