Make Changes to a Wordpress Website

I have a single-page website based on this template: [login to view URL] CHANGES 1) I have an image of a 2017 Calendar which needs to be replaced with an image of a 2018 Calendar 2) The "ADD TO CART" Paypal button for the 2017 Calendar needs to be replaced with the code for the 2018 "ADD TO CART" Paypal button 3) I have a video from Youtube which I need to replace with another Youtube video from my account. 4) I need to replace a background image (The starry nights over the mountains) 5) I need a new title which says "UPCOMING EVENTS" although the link will just be "EVENTS" Here I need a table showing the date of the event, the name of the event, the address of the event and a column which shows if I will be speaking at the event or not. I have already created the table in a spreadsheet. There are only 5 events at the moment but I would like there to be space for 8 just in case. 6) I have 3 items which have a "READ MORE" link. On a separate page I would like to have some text explaining how I created each image. I have that text on a separate Word document. 7) On MY website I have a link called "GUIDANCE". I would like this to be replaced with the title "TOP 10s" I would like this link to go to the same separate page as (6). 8) I downloaded my website to a zipped file a few years ago. The "TOP 10s" link was a list of "Ten Top 10s". I cannot remember what they were but I need someone to open the zipped site, find the text and copy the ten lists onto the new page. I will send the new text, the new images, the Paypal button codes, the links for the Youtube videos, the table of events and the zipped files when the job is awarded. Any questions please ask and I will get back to you quickly. Thanks!
