Modernize website currently using custom wordpress theme

The company has an existing website as identified in the attached txt file. The site was constructed by a developer in 2013 using a custom-built wordpress theme. The goal of this project is to improve or replace the theme etc. so that the site meets modern standards of web design, including but not limited to being a responsive website that is mobile-friendly, updating theme files and styles without losing content or subdomains. Currently there is very little hosted video content, as most is embedded. Image content should be carefully managed if affected by the transition, and existing use of plugins should be documented to ensure no loss of features or functions in the case of improvement or replacement. Installation of new site shall not require developer cpanel access to ISP even though that would be an admittedly easier process. Existing site shall be fully archived as necessary while staging area is created on our server rather than developer server unless otherwise agreed. A new template design to replace the existing gold bokeh is encouraged but not required, though the same general style and brand should be maintained and possibly reinforced more dramatically and memorably. Bidding: NO SUBCONTRACTORS WITHOUT WRITTEN PERMISSION. In your response/bid, it must be absolutely clear that you read the project, looked at the file(s), if any, and have something intelligent, clear, or informative to say about what you saw, or you will not be considered. If a project requires a delay from either party before starting or accepting work, please build that time into the proposed number of days in your bid. This way you will be able to accept the award at any time before the actual official start of work. Do not bid low, ask to talk, and then increase bid. This will be counted against you. Instead, bid properly (or high) first and then ask to talk. Please do not expect or request bonus payments; bid high instead. A bidder should identify status as a single freelancer or part of a team using a shared account. Some projects may be too risky to entrust to rotating team members who will not be able to efficiently maintain the consistency of knowledge throughout changes on complex projects. Other projects may be sensitive enough where a single point of accountability limits risk of compound error. Failure to identify status will result in a negative presumption. Please do not reply with long boiler plate messages or credentials, or we will suspect an automated reply and it will count against you. Asking any kind of question showing your insight into the project outcome is considered a major plus. Security: There should be no expectation for five star ratings, cpanel access, paypal, or use of skype or any other communication outside this venue. Work Ethics: Please do not ask for work to be reviewed when you have not meticulously reviewed it yourself. All work files must be delivered at end of project, including all files and source code used to make the final product. If the project involves visual design of a website, the mockup should look like the intended finished product, not a demo or shell. Do not use inapplicable placeholder images or text on any version of a server-installed site without prior approval. Bidder should be available for office hours at 1pm, 2pm, or 11pm USA-New York City time. In military time that would be 1300, 1400, or 2300 USA-New York City time.
