Not really. Nowadays, it is generally considered unsafe to share personal information such as phone numbers with resume writing services. Instead of your phone number, you should share your email id, so that if there is any doubt with the resume they can clarify it through email.

It is used in place of an objective statement. An employer may not read your entireresume. A summary will give them a snapshot of your work experiences, achievements, and skills. To be effective, it should be very brief (4-5 lines of text).

In short -- a "W2" ( IRS tax forms) contract means you are treated as an hourly employee. You will paid for the hours you work, but your employer will deduct Federal, State and Local income taxes from your pay, as well as public health, pension and disability insurance.
