This is something that you cannot do by yourself, and I am always amazed when something thinks that they can! A novice has no idea of how the tree will react to cutting, how to climb safely with a chain saw, where and how to make the cuts, how to decide where the pieces may fall.

The rule of thumb for a novice is that if you cannot make the cuts with both feet on the ground, then you need to call someone else. Wood can be extremely reactive.

A pro would probably fell it in pieces, roping off each segment and lowering it to the ground while he remained safely and securely tied to the remaining portion. Pros know how to take down trees with minimal danger to themselves, yet many are killed or maimed each year.

Don't be stupid. Get the $500 bucks from somewhere.

You definitely have to get a professional service. It is expensive, but saving the $500 is not worth a potentially fatal injury. This is way too big a job to attempt by yourself.

Write the check.

One trip to the ER with a minor injury will cost more than $500.
