Even if you take them far enough away that they don't come back if you don't do the exclusion some more bats will find the shop. To solve the problem you have to do the exclusion. Besides being easier on the bat if you exclude them they check your work. If after a week you still have bats you know your job is not done. On the entenet, here, bat conservation international, Robb Russells wildlife pro network, nwcoa.info there is plenty of info on how to do it.
If it's your first bat job I would consider hiring a friendly wco that has done it to help you. If you don't know anyone you need to make some more friends. Some people call it networking I call it making friends.
If you must relocate pesky's idea is a cheap one that will work for catching them.
All this advice from everyone is moot if you are talking about an open shop area then you are going to have to haze and or habitat modification.
