Wordpress developer services needed

I have created a membership website using wordpress. I am looking for someone to help me continue developing my website to my specifications and needs. I would also like to find the right person to not only do the above stated tasks, but also stay on board for fututre needs as well as customer service / admin support.

Please asnwer these questions to be considered for the job:

1. When can you start?
2. Are you willing to do work for an extended amount of time?
3. Do you have examples of Wordpress development that you have done in the past? Can you share an example with me?

Thank you for your consideration.
Rick
