Assuming you are referrring to EasySiteWizard Pro, to create a simple form you will need the following:
Firstly set method to POST and add your email address in the box.
Now you will need some input fields - decide how much information you need from your customers and drag a text field onto the form for each one. Eg, one each for Name, email address, phone number, etc. Add text to each one and make sure each one has valid INPUT NAME.
You may want to add a text area for comments. This is basically a larger text box. Again add the text beside it and give it an input name.
Lastly, you will want to add a button. Give it a VALUE like "submit" or "send" or whatever text you want to appear on it.
This should be enough for a basic contact form.
With regards to a calendar, there is no such service provided unfortunately.
