adobe signature

hi,

really sorry new to all this, and I apologies if this has been covered but I cannot see it anywhere.

I own a small alarm company and we use adobe e-signature on some occasions.

I wanted to ask is anyone aware of a similar product but with the ability for us to add costs in and the ability for the form to add or subtract if the client chooses options on the form.

e.g option1               10.00          tick box if required

     option 2               30.00          tick box if required

     total to be added up and shown In a total box below.

does anyone know of a product that does this ??
