Get yourselves a permanent roadie. Either a muscular guy or a biker girl -- gender doesn't matter. Some of the best roadies are females (ask Twisted Sister or The Fast about that one). You need protection from flying bottles. Not everyone is going to like you. Not every venue will be what you believed it to be. Try to stick with large venues. Be flexible.
You will need a manager to assess your situation. You have a nice gig lineup. There are two in the PA. area who might be interested if they heard you.
I will let you know how to find them shortly.
