remove bugs and improve my website

Hi, My website: [login to view URL] (Magento) 1) We should add a menu that is customizable allowing us to present our services much more easily For example : - Home - Vacation rentals (our apartments on the site) - Long term rental (return to real estate site) - For sales (idem) - Projects (idem) - Contacts us etc ... 2) It would be necessary to cancel the registration which will have to be necessary only if the person Book an apartment and is really ready to pay 3) The payment must not be on the totality of the reservation, but only on 20%, it will of course be necessary to specify it somewhere 4) When the visitor presses on "Contact Host", it should be directed to a simple form (name, email, telephone) in order to retrieve lead and contact him more quickly 5) When an apartment is returned by a registered visitor, we receive an email but no details provided us (name, email, tel, title of the apartment etc ...). This will allow us faster responsiveness 6) When a visitor enters check in check out dates on the home page, or even on the page, where are all the apartments, if he is interested in an apartment and clicks on it, he must enter again the dates. The dates should be recorded and reported on each apartment he will visit 7) Bug 1: when a visitor views the slideshow of the photos of an apartment, there is no way to return to the apartment listing 8) Bug 2: There is a problem on the appearance of the flats, once they appear, and another time not, in a random and illogical way. 9) Bug 3: The map randomly appears not exactly, once it fits well on the area where are all the apartments, another time we see all Africa or even sometimes we see the whole world. 10) Bug 4: I would have to adapt the photos in all the contexts where they appear: - On the list of apartments - In landscape, on the presentation of an apartment - On the slide show 11) We would like to see the prices that appear on the thumbnails of the apartments according to the dates proposed by the visitor. For example: an apartment costs $ 100 per night, if the visitor returns dates for 5 nights, then will appear $ 500 on the apartment sticker If he did not put any date, we will see "Start from" with the minimum price Thank you CB
