Is there a way to insert my signature in a contract that I make with a client?

If you are referring to add your own signature to form as a form owner, you can do it in two ways.

First:

You can add an  image of your signature using an image field type. Here is a screenshot for reference:

In this way, your signature will be already present in the form and then the person filling up the form will place his signature and submit the form. 

Second:

You can use an Adobe Sign integration field. It has an 'Activate Signer Flow' option. When that option is enabled, the form respondent will be asked to sign the document; afterward, the owner of the form will be asked to sign.

Both parties will then receive the signed document as a PDF.
