This honestly shouldn't be too difficult for someone who knows PHP. I'm a Ruby on Rails guy myself... doing a side project for one of our clients and I just don't understand PHP well enough to do this efficiently. Basically I have a punch list of things I need to accomplish. An example is swapping out some "before send" hooks for the contact form 7 plugin and putting in Gravity forms versions of those "hooks". So far I'm pretty happy with my staging environment and github integration for version control... but always open to suggestions there as well. Estimated budget is just a number I had to select, we can discuss pricing once we go over what needs to be done. Thanks.
