In similar situations I've deferred to the verse, "Delight yourself in the Lord and He will give you the desires of your heart."
If we delight in Him, then our heart's desire is to bring Him glory, and its a sure bet that will happen.
If we don't delight in Him, then the desires of our heart are to glorify ourselves, and there's not a whole lot of joy found there.
So as scary as it may be, if you are delighting in Him ... which asking all of us to pray may be a good indicator ... then its a matter of faith to step forward, and trust in Him.
Its wise to consider the times, and the costs, but we're never called to make decisions in fear, so don't let that cloud your judgment. If you do this, do so consecrating your business to Him, and strive to glorify Him in every decision.
FWIW, I sold everything and dragged my family to Somalia a few years back. It was tough, but some of our best memories, and it was through that decision that He showed me the step after which brought me to where I am today.
