I am interested in finding out the cost and timeframes to develop a website (which I will call for now WebsiteA) similar to the following: http://www.carsales.com.au/ or https://www.realestate.com.au/. The products to be sold on WebsiteA are not cars or real estate. The products on WebsiteA will be numerous and have various levels similar to the 2 websites mentioned above.
I am also interested in finding out the cost to develop an APP for WebsiteA as well. Again the APP would be very similar to the APPS for the exmaple websites above and can be found in the Apple store.
WebsiteA and the APP will also need to have e-commerce, credit payment facilities, be very secure, have a login section where people selling their products can enter information and add photos.
Most of the design and design direction will be supplied by my graphic designer, but help here may be required as well.
If the job is done to a high standard then there may be ongoing support available as well.
