Make changes to ASP.net site

I run stuckforstaff.co.uk and I need some updates to the website.

- I need changes made to the search page for agencies (https://stuckforstaff.co.uk/branch/search.aspx?new=true). At the moment the search only includes results from users who have a paid subscription, but I would like to update this to include users *without* a subscription (as I am demonetising the site for staff) - giving more results to agencies.

- There is a mailing list creation module in the admin backend that we use to send emails to users. I need changes to be made to what kind of user the mailing list includes in the search. At the moment it includes people who have *opted out*, I need this changed so that people who are opted-out are *not* included. Also, I need it to include staff who have not paid a subscription.

- The Jobs Board is not formatted properly: https://stuckforstaff.co.uk/staff/jobs-board.aspx. Some area headings are missing and it is confusing for users. If you click on 'Greater London' at the top - it jumps to the jobs and you can see the heading 'Greater London'. But if you click on 'Scotland (Central and South)', it jumps to the jobs but does NOT display the heading 'Scotland (Central and South)'.

- I need the Top Rated staff section removed from the front page: https://stuckforstaff.co.uk/index.aspx?no-redirect=1

- There are two pop ups that appear when staff log in (see screenshot) - I would like these pop ups removed.

I am looking for someone experienced in ASP.net and who can create clean code.

Changes will need to be uploaded to our Github repository.

I'm hoping to build a relationship with a good programmer and do lots more work in the future.
