Hi there,
I can implement your e-mail gateway for you.
If you have a VPS (not shared hosting), chances are you will not need to use an external e-mail provider. If you are using shared hosting we will need to move your site to a VPS (the cost is about the same as shared hosting, ~$10 a month for a basic server). If you don't already have a VPS, I can set one up for you as part of the project for an additional £15.
I'm a professional developer, and system Administrator, so would be able to get the job completed professionally for you and in good time.
I can also make a video to show you how to configure the settings for future use.
We are in the same timezone which will be useful for communication.
I am dedicated to every project I work on, and this is reflected in my feedback, please see my profile if you would like to read some feedback.
Best,
Gary
