My first hourly contract! Let me know what you think.

Hi all,

I'm about to present my first hourly contract to my client. This is a very flexible client, one I have a good relationship with, so having an an airtight contract isn't a must.

But it IS my first hourly contract and I am really wondering whether or not my language and offer for hourly work is reasonable and appropriate.

Is it common to use the language and hourly payment terms I have written up? Would it be reasonable to present it in that format (estimation and reevaluation for +/- 10% of estimation)

Check out my contract here. All feedback is appreciated.

Thanks!
