Guessing Cunningham and Bennett are on close to 20k per week each, that's 2 million a year in wages between them.

I'd be tempted to offer Crewe £1 millon for the pair of fullbacks (Ng and Pickering), and assuming their wages would be less than 10k each then the deal pays for itself, we have 2 positions sorted, and some young players who might actually increase in value
