expert in prestashop

I have a project with several tasks. Please give me a price for each task then a price for the entire project. This will help me to decide what task to do or not. Here are the tasks: To-Do-List for the maintenance of [login to view URL] (Updated 09/10/2018) 1. The SEND button under “Contact us” suddenly disappeared. Please re-instate. 2. Too many spam emails received, we need to add a code to block the spamming crawlers and spiders in the “contact us” and the link exchange forms. 3. I need to add “Abandoned Cart reminder” and the right cron to remind potential customers on their products they placed in the cart and offer them discounts if necessary. Hopefully, they will accept the offers and become customers. Please read this [login to view URL] 4. Where the “currencies and languages” are now placed are not seen by all the site visitors. Please place it in a better place and add the same info on the product page, anywhere around the price where it can clearly be seen. Alternatively, you can place it in such as way visitors can easily see it (maybe never gets hidden when scrolling down). I receive lots of emails requesting the price in euros, while they could’ve just clicked on the Euro symbol. Obviously, they missed it. 5. I am getting lots of spam in the forum. Maybe this is way too old. Please upgrade or remove. 6. Clean the website, improve SEO and speed especially the home/landing page. 7. When I click on the home pictures or the side advertisement pictures, I should be taken to either a web page or send an email depending on how I set it in the back office. Example: [login to view URL] or mailto:bsh@[login to view URL] 8. Finally, if it is simpler to just upgrade to the latest and most stable version of prestashop, which is not necessarily the latest version; please go ahead. Hopefully this will fix lots of the bugs and malfunctions that I listed above. 9. Freshen up the front office with minor changes and colours to give it a new look but the same structure. I need a price for each task and another for the whole project.
