End to end testing of a Saas

You will be sent the signup page and, from there, its over to you!

Need to feedback each of the below - all of these would be as both an admin and a normal user:

1) Bugs - things that simply did not work
2) User experience - things that did not make sense/were confusing but they worked. If they do not make sense then make suggestions how to improve - it could be product changes or it could be adding a popup, a video, a tool tip etc.
3) User interface - things that looked wrong/out of place. This could be due to screen size, browser, OS, screen zoom levels etc so you should be testing in more than once device/OS/browser combination
4) Security issues - URL manipulation, ability to view unauthorised pages and so on
5) Anything else you can find/think of

Output should be a spreadsheet with the URL, section, issue heading, issue detail, category, image (if relevant) etc. If a video makes it easier to understand the issue then great but it still needs recorded in a spreadsheet

Need someone with a real eye for detail - to the level of looking at a formatted bullet list and noticing that the text is not perfectly left aligned due to 1 being narrower than 2...

Budget is flexible - looking for more than one person
