As you say it would be a good idea to contact you local beekeeping association and I dare say you will have a good response of interested beekeepers.
It is not too late to move the bees, the only time you should not move them is in the Winter, as they are clustered to keep warm and need to stay over or very near to their stores (honey). So, at this time of the year, they can be moved, the question is how much forage their is for them in your area, they will need a good source of nectar and pollen, right now in the country side it is often OSR, your meadow may have some flowers they can forage, for example white clover, but some flowers the nectaries are too deep for the honeybee.
Hope that helps.
