Hello mr (mrs)
Based on what I understood of your project, you need a site where you can publish information about your Coffe Kiosk, history, contacts, promos but all that as information, not a transactional site as a shopping cart.
If what I have exposed before is what you really need and assuming that you are going to pay for your favorite web hosting and domain provider or even better, you already have it, the price could be lower than you think.
There is different ways to do it (web hosting and domain not included):
1)We can install an script to use something like joomla, wordpress or any other script that you prefer, and this could be the cheaper option, because there won't be any kind development or will be few (could be just configuration) and implementation. In this case, we will be talking around $200-250USD
2)Develop the site from zero
This means that we are going to create or implement the design that you want for the front end page, create the data base, create the code for the site, test it, user aceptation test, capacition or manuals and the support for a short time. ($250-$450 USD)
My bid is based on the first option but we can always talk about the cost, the scope and the time for the project.
We are a team that have enought experience in web development so if you need to know anything else or you're interested in my offer, feel free to ask whatever you need.
My best regards,
Elionay
PM and Developer
