Hi,

Existing Wordpress website to be updated. The Website is www.excelpropertyinvestments.co.uk

1) https://excelpropertyinvestments.co.uk/station-court/ This page to have existing enquiry section removed & updated with a new widget which I will send you the code for
2) https://excelpropertyinvestments.co.uk/riverside/ This page to have existing enquiry section removed & updated with a new widget which I will send you the code for
3) https://excelpropertyinvestments.co.uk/castle-view/ This page is to be removed from the website
4) Photos to be updated across the site which I will send you
5) Site to be made mobile friendly
6) Advise how powered by Wordpress.com can be removed from footer on each page
7) Remove powered by Wordpress.com once I approve the solution
8) https://excelpropertyinvestments.co.uk/home/contact/ Dropdown option to be made available with a new tab called Guest Information. I will forward a separate document to copy & paste the text required on the page.

Can you let me know a price & how many days to complete?
