Consulting for small PHP/API integration jobs

We currently have a fairly minimal level of integration between our TNEW site and our Wordpress-based main website. We will likely be doing a complete web refresh in a year or two, so we're probably not going to do major changes in our technology stack/code base right now. But there are a few little things (the most pressing related to easy signup/preference management for e-mail lists) that we'd like to develop API solutions for, ideally using code that is congruent with our existing bias toward Wordpress/PHP.

We don't have a ton of experience with this, and we're also pretty flat out. So we'd love to contract this out to to someone. Question:

1. Within the network of ecosystem partners, are there any web agencies that will take on small jobs like this at a reasonable cost (as opposed to only wanting to do complete redesigns or charging excessive overhead on small projects - can you tell we've occasionally been burned before?)

and/or

2. Can anyone recommend any smaller scale developers (solo or side hustle?) who might have the expertise with Tess and PHP to take on this sort of thing? 

Happy to discuss here or offline - my e-mail is ddwiggins@historicnewengland.org.
