Dear Jack Martinez,
Thank you for sending me a copy of the proposed contract. I just wanted to bring up an item for revision before we finalize and sign it. During our initial conversation, we agreed that all expenses I incur for the purchase of equipment necessary for the completion of the project will be shouldered by the company. I believe that this should include basic office equipment and supplies, such as those used for printing and documentation. Can we please include this as soon as possible? If you would like to discuss this further, though, feel free to call met 434-3434. Thank you very much.
