Just a few observations:
1. You do not need a spiritual advisor "to hear God's voice" if you are genuinely a child of God and have the indwelling Holy Spirit to lead and guide you (1 Jn 2:20,27).
2. If you are in a true Bible church, you should have elders in your church. They are there to "watch for your soul" (Heb 13:17) so they are the ones who should be approached when you need spiritual guidance.
3. You will not find any Scripture telling you "to seek vision" when you pray. God has already given the Church a vision, which is to preach the Gospel to the whole world (Mt 28:18-20; Mk 16:15,16).
4. God's "voice" is in His Word, which is a living Word and a powerful Word (Heb 4:12,13). He will also speak to you in your soul (Rev 3:20) as you commune with Him. To "sup" with Christ is to have communion with Him. More important than just "hearing His voice" is to obey His commandments (1 Jn 2:3-17).
