Create a CRM SaaS specifically for Merchant Processing Sales Offices

My company is looking for a freelancer to create a CRM specifically for our merchant processing sales offices. The CRM will need to be built for web platforms and will need to store processing data. We already have existing CRM software in use, but we are looking for a more tailored solution for our specific sales offices. Must have prior experience with Bank crm builds, PCI DSS Level 1 Certification, must be familiar and have passed a SOC 2 Type 2 Audit, and be able to show examples documenting these items. Does not need to be from scratch, im open to plugins for some features, but it must be tailored to Merchant Processing, no generic Monday or Zoho, etc. The standard wireframe is fine, its more the use that needs to be specific.
