Hi, we are looking for some help in developing a website which we are using a pre-defined theme with. We already have most of the concepts ready and are using the Venus Bazic theme to help simplify the development of it. We require some additional help on an hourly basis to help fix some of the technical issues we are still facing and would need someone who has experience of working with themes to help us out. Paid on an hourly basis, we would hope for this to be an ongoing relationship, although we would expect a good response time for issues. Initially we would be expecting there to be at least 15 hours a week for 2 weeks. We would then review the situation and be looking for a much longer relationship to ensue if all is well. Thanks for your interest.
