I probably wasn't clear enough - if he can get the questionaires completed and prove there is an interest in the services, it will aid his application for a loan.
He has even said as much himself about funding being reliant on the questionaires.

As you say, he needs to produce evidence and costings, predicted revenue too - which will hopefully add weight to the argument.

I imagine he will need to be creative with his pricing policy to attract customers as the £50 per week commuter costs in addition to any additional costs to get to points beyond the Spirit Bus network, is quite steep. It's almost 'GNEesque'!
