Required Wordpress freelancer for Updates on Wordpress Website (Sticky Header + Drop Down, Pricing Page, ROI calculator) job

We have 2 Wordpress Websites:
1. NZ
2. AU

They are not connected. So if I make a change in 1 website - I'll have to make the same change in the second one manually.

All the overview of what we are trying to achieve below is for 2 websites.

1. Make the Header sticky with 2 phone numbers in the header

2. Make sure that we can add Dropdown pages in the sticky header Menu if we want to and more Menu items if we need to

3. Pricing Page - We currently do not have one and we do not like the Wordpress Pricing Widgets.

4. Also on the pricing page, we would like to have this formula (removed by Toogit admin)
Currently, it looks terrible, so we need to make it look more user-friendly.

Looking into all this, please provide us a Quote/Estimate of how long it will take to build this on both websites.

Thanks
