I have extensive experience customizing websites and have no problem doing what you requested. It also sounds like you have all your content prepared, which is a huge help to make this process go smoothly.
I know what it means for a business owner to have changes made immediately. You don't want to worry about it and just have it completed, I can do what you've requested so you don't need to worry about it.
After the project is finished, if you are happy with my performance, I can provide you with webmaster services. I can do these maintenance requests for you as they are needed in the future. This way, I can get familiar with your website during this request, making future changes easier to complete as well as cheaper for you.
