Hi, I'm looking for someone to change cracked plugins from my WordPress website to free plugins but maintain the same design. It's important to me that the design stays the same, so you'll need to provide the same functionality using a free plugin. This could be an existing plugin that you'd need to customize or you could create your own plugin from scratch. No matter the approach, I'm confident you can help me with this project. Thanks for taking the time to read my description, and I look forward to hearing from you soon. Website URL is watchonlinefree.in. Now crack plugins are giving issues.

I would like a design, preferably in EasyEDA that can be created and assembled by JL PCB (or somewhere similar if you know of a better solution). The board will need to include pin headers to plug in an esp32 dev board as well as a raspberry pi zero. The i/o on these boards are then used to control a relay and a few other simple devices that use the i/o. There are a few incoming connections like a usb serial connection, power, and wires that the relay shorts. I will need some advice on the best/cheapest way to handle some of the functionality, like whether we should just put pin headers to plug in a pre-fabbed unit or build it into the board. Please provide at least a ballpark amount that you charge for these kind of projects and then we can discuss in more detail before settling ...
