Let's get your site going! While I may be new to Freelancer, I'm not new building great WordPress sites.
We can definitely get your Product Bundle updates done quickly. Since I don't know yet what kind of changes you're looking for, I would say a few days. But if there are not that many changes, it could be done sooner.
Any charges for themes and plugins are not included in my proposal.
One thing that sets me apart is being up front and prompt in my communications. Message me and we'll have a quick chat to get things started. :)
I start on your site soon after you award the contract.
Talk soon,
Roger
