Good evening, and thank you for letting me to bid in your project.
As I understand, you need an HR virtual assistance to accomplish all the required tasks, I don't see a problem in work 20 hours / week in your project. This is a great job opportunity for my job background, and I'm more than glad to help you with this.
I'll be available anytime you want, since I don't have a fixed job, we have a small office in El Salvador (a group of friends trying to start a business), but we are dedicated to the projects all day long, including weekends.
At this time, we are in -6:00 GMT, but we can optimize our time to work in the desired schedule.
I'll be awaiting for your contact so we can discuss your project and start working together.
Thanks in advance for your time.
Regards
Javier
