Recruiter , 1 to 3 hours work per week only

We are a small software placement company. We have a few hot openings, but do not have the time to make phone calls with the candidates and client contact. We are looking for a recruiter who only need to work 1-3 hours per week. We will do the ground work of identifying the candidates for our openings. We will also handle the email communications. You need to make some phone calls to talk to the candidates as well as clients following our instructions. You need to use your own US phone number. If you are interested, please write a proposal and mention that you have a US phone number that you are willing to use on the very first statement of your proposal. Also mention what is your available window of time in US time zone. Thank you for your time.
