Hi There,
So, what I understood is you'll need a website where a user can make his profile, submit a portfolio (only one item, it's price and time) and a customer can purchase that item/service directly using PayPal, Commission of sales to website owner.
The above can be achieved in 12 days investing USD 1000, that covers:
1. basic functionality
2. html design
3. Architecture : HTML5, CSS3, PHP CodeIgniter
4. Commission of sales to website owner
Adding a USD 1000 to above will add following things:
1. Admin to manage site
2. Angular JS front end to make site respond quickly on front end.
3. Extra features that can be disclosed when we speak
All prices will have a + 10%.
Please don't message if my prices seems higher.
Thanks,
S
