Salesforce developer

We are a garden rooms company (www.smartspaces.c.uk) and have a new website. We need the forms to be integrated into Salesforce so new leads come in with the all the information on the forms. The fields already exist in salesforce to link with. There are 4 forms to integrate.

We also want a welcome email to go out once a new lead is submitted.

We will want other ongoing work, but this is the priority

We want someone who is Salesforce Dev Certified
