OK, reality check! Raising queens from eggs is possible, but not something for year one. You need to get to know your bees and beekeeping a bit more before making your beekeeping more complex than it has to be. If Andrew (he reads the forum from time to time by the way) is prepared to honour you with more of his stock, then go with that for now. Inbreeding is a risk but if you are getting two more stocks from him them start with that. You will need to ensure that they build up enough to survive the winter. If you currently have one colony then you can still raise nucs from that one, but would need to widen the genepool for the next generation. However your bigger and more immediate problem might be simply having enough drones and enough good flying days for mating. If I remember right the Shetland beekeeper resorts to AI to get his queens mated.
