I got my A+ in ~2000 as part of a job I worked for (doing technical support). At the time, A+ never expired and was considered good for life. It never helped me get a job and no one ever asked me about having it. I did end up going the software route instead of hardware, so that probably played a big part.
As someone already said, it's baseline "I am knowledgeable about IT." If you're just starting out, I would consider getting it. Otherwise, not worth it IMO.
First, this is a great idea, and congratulations on hitting $8k/mo in revenue. The fact that you've stuck with the business for this long and grown it is great, and better than most people do.
I Strongly recommend engaging directly with your customers whenever/wherever possible (Twitter, Slack, Discord, etc). One thing I immediately noticed on Twitter is that your name overlaps with a email newsletter published by @Doctor_V
Lastly, I would do a quick read over of your site and content. If you're going to start advertising, make sure everything is professional. For example, when I opened the link, I immediately noticed this:
"with [email protected] be" - that missing space between .com and will is super glaring for someone like me. Make sure you clean that stuff up before you start advertising. When I see that kind of stuff, I go from "this is a professional service I might pay for" to "this is not a real business." I know it seems small, but just being honest.
When I worked in Forex (~1999-2003) this was common practice, at least where I worked. Bring in customers, teach them the bare minimum, and let them trade with 100:1 (and sometimes 200:1 leverage). Even better, because 99% of customers lose, we would "assume the risk" of most trades, accepting their trades but not offloading them to larger banks (ABN, Deutsche, etc), so their loss was all profit. If someone demonstrated they were a decent trader (very, very rare), we would set a special bit on their account and, from then on, offload their trades to major banks at better spreads than we offered to the customer, making 5-10 pips per transaction. Most of the "decent" traders traded in huge lots (10-100 millions), so making 5-10 pips per transaction was substantial. Long story short, you make money on the crappy traders and on the good traders, and the good traders were even better because they would keep coming back.
