They sent me a letter stating, tree overhang over power lines.

Any idea how much is normal to clear brush/trees on vacant land?

B and B+ properties for the most part here: We usually highly recommend it and give examples of what is NOT covered (tree falling on their car, break-in, the old fish tank leaking onto their laptop, etc) and highlight that when they sign the lease, even have them initialing the highlighted sentence. 

This week so far has been tree limb down on power line, sewer back up.

Once again be careful because the fasteners and accessories may not react well to the use of these chemicals.The best thing to do is to get as much sun on the roof as possible (Cut trees away) and keep debris such as needles and leaves off of it.

Not good, need licensing etc.Or am I completely barking up the wrong tree.

You need to use a pic that describes yourself too, you want to come across as a professional, not as a highschool beauty queen, not as model holding up a tree, this is not a year booK picture.

Recently I witnessed a robbery at gun point of the section 8 neighbors right in front of my home as I looked out of my front door window at about 1:05 am Sat. morning on June 12,2010.We hate these neighbors and I know that this a strong word but what else can we do to get rid of these people before they endanger somone else or my 3 daughters and myself or my elderly mom could be the next victims or be killed?

Don't harass my client or we will take further action, don't speak to my client or we will take further legal action, don't discriminate against my client or we will take further legal action, trim the tree or you could face legal action, don't run over my client or you could face legal action. etc. etc. 

Upstairs units have nice private balconies overlooking tree-lined street.
