BuildSavers

I want look at the cost to create a building materials supply app. I have worked on Wix a lot but would like something quick and simple put together. My location is South africa Opening page needs to have a name at top 'BuildSavers' at the bottom needs to have WhatsApp link 0781311000 and must have two main boxes one the creative picture of building materials named quick material supply Street cost. The other box needs a creative picture for construction-related hire equipment and the name of the box needs to be site prep, tools and hire. Further down the page scroll 6 more boxes one being primers and additives with pictures of paintings second one waterproofing with images of tins and rolls of waterproofing material the third one foundations and slabs maybe picture of her concrete floor slab or suspended slab third one doors and windows related to aluminium or steel windows and doors pictures 51 copper and PVC piping pictures of copper and PVC pipes the sixth one roofing. Which of these blocks would link to a second page. On the quick material supply cost there will be a list of building materials with a drop down menu for each for example bricks would be clay cement or face brick in a quantity amount. once the selections have been made then there's a add to cart icon which would take the user to a page for example with three or four different types of bricks with the pricing and product descriptions. This process needs to be very simple and seamless so suggestions are welcome. the list would typically start from the beginning of a project to items used at the end of a project . These would be simply text list with selection dropdowns. One would be able to send that to a predetermined email address or to WhatsApp or even a printer there should be a chat icon on the front on all pages. All communication should be text based or chat based. There needs to be a registration page which would identify the location and would have some tick boxes to assess accessibility to the site small bakkie or van only 4 ton 6 and 12 ton truck interlink truck with crane tar road or gravel road etc a space to type in other details / place to type in the site managers name and contact number and a place to provide the authorised buyer decision makers name and cell phone number. There also needs to be an about page which I'll give a description for. Also needs a very simple registration page name mobile site address this address shouldn't be provided in the form of a location pin
