Barclaycard epdq payment integration with Gravity Forms

We have a WordPress website which has few forms running on GravityForms. We need to integrate Barclaycard epdq with gravityforms.

Integration has to be in a way which if we create any additional forms, this payment gateway has to also be enabled and working.

- You need to be familiar with gravityforms with working knowledge how this plugin works
- Solid WordPress and php knowledge

Send me your proposal, including:
- Total cost
- Duration to how long it will take (fully tested)
- What requirements you require

I will create a test WordPress account with the same forms running so that you'll be able to test.
