Hello I have a couple of ideas for my website but I think someone to help me code them and import them into my website. So basically it's like a raffle or more like a lottery the customers who purchase the product will receive a unique code with it e.g U21SA162S something like this or whatever and they have to submit it into our Raffle page in order to qualify for the prize draw. So I will need something like a valid code generator and the form to recognize the valid codes. Also like a calendar with booking for the date of the event that will happen on a certain date like for example having a calendar on a page and when the click on the certain date (coloured date with the name of the event) it will be like an embed window showing some info and then a button to make a payment in order to attend. How much would it cost to be done?
