Prestashop work

General information for the website: online lingerie store
Description of requirements/features:

www.eyecandylingerie.uk

all the info for my products are being pulled from my supplier using a module, however all the text is in french and my prestashop seems to be defaulted to french also, i need it all to be in english if possible. if not i will do this manually.

i need images adding to my categories and sub cats and a small description of each category

i need to make sure the site is running at its fastest and best OPTIMIZATION

i need payment set up so i can take payments from customers. paypal will be fine. - someone has already made a start on this but i get an error message on my check out
Error occurred:
Please try to contact the merchant:

PayPal response: Error


if possible utilise the google rankings i have already from my old site (www.eyecandylingerie.co.uk) i think this might be a 301 redirect? not sure?
i think that links need to be set up on my old site to the items on my old site. so if i type in "leg avenue corset" in google it comes up with
Leg Avenue Vivian Corset 86514 - Eye Candy Lingerie
www.eyecandylingerie.co.uk › ... › STARNET › LEG AVENUE
Vivian Corset features velvet trimmed satin silhouette with support boning and side zipper glitter side ... Size Guide for Leg Avenue Lingerie & Hosiery Brand ...
i want this to go to the same product but on my new site

size guides for each brand to be added to my products as used on my suppliers site (see attached)

add videos for products that have them on my suppliers site (to do this automatically for new products also if possible) see attached

any other work you may think is required to make my shop better and higher with rankings

teach me how to upload new products using a spreadsheet

set my shop as live once all tasks are done

set for mobile view option also
