Get a Website Built

I am looking to build a personalised invitation web site, similar to [login to view URL] You can use a tool/technology(ies) of your choice - wordpress, PHP, whatever. Requirements: 1. Approx. 150 names/email addresses entered into a small database/CMS 2. Invitations sent out to these email addresses with personalised text and unique URI 3. When a person clicks on the link in the invite (using browser on PC/Mac, iOS or Android device), it opens web site landing page 4. Landing page looks like Pokemon Go screen: green lawn with a pokeball on it [there are plenty of png/psd files on deviantart, etc] 5. Once you click on a pokeball, it opens up and a standard invitation page slips out 6. At the bottom of the invitation there is a "tick" and a "cross" icons. 7. Once you click on any of the icons, sign "thank you" comes up and response is recorded in the database against this person/email. [you will need to work out how to pass unique ID from a database in the URI path or in the header to form the email invite and then into the web page, so that unique response is recorded] 8. If you open the same link later on and change response, initial one will be overwritten [i.e. database can have either Yes or No response, but not both] *********** There will be 2 invitations with overlapping but different distribution list. You can either build 2x databases and 2x landing pages, or use the same one and create a new table instead [for example] - whatever is easier. *********** Please provide your pricing and estimated time to complete the work.
