Send mail based on submission data from another form?

Send mail based on submission data from another form?

I maintain 2 forms in order to match buyers and sellers. 1 form contains data from the buyer, and the other contains data from the seller.  When a buyer submits their info into the form, I would like a form automatically sent to the sellers based on certain matching info from the buyer.  For example, if a buyer is from California, I would like an email automatically sent to all sellers who are also from California.  Is this possible?  If so, can someone please help me with the script?

Thank you!
