Website Design - Template Customisation

Website Specification

I currently purchased a responsive web template, in HTML5 and CSS3, which is built on top of bootstrap 4. You can see a preview of the template here:

I don't have time to get the site up and running, so I would like it customising as follows


Logo: I would like a logo created for the site and added to the header

Header: The header should have the following links (and sub links):
- IT Consulting (This will link to a summary page)
-- Website Management
-- Speed Optimisation
-- Search Engine Optimisation
-- Custom Programming
-- Malware Cleaning
-- Server Security
- Engineering (This will link to a summray page)
-- Project Management
-- Mechanical Engineering
-- Process Engineering
-- Expert Witness
- Contact
- Login to Client Site

I would like the Login to look separate, like it does at the moment.

The two summary pages I would like to look like the features page (https://jituchauhan.com/inspirelite/#features), although I will need to write a little more text, so will have to see how that fits as will probably need less rows?

The other pages I would like to look like the blog pages, with a few exceptions but as we go through the project I can go through that with you.

As I said the pages already exist out there it is just the customisation and importantly adding images to make the site more interesting and customised as at the moment although it looks clean which I like it just needs to be customised.

I am looking for this to be done over the course of 2-4 weeks so no immediate rush as I would prefer a good job.
I know enough code that I can update the contents etc.

Realistically if you imagine the site as a virtual CV
