When you discover you might have bitten off more than you can chew with an openwrt set up, anyone used a remote assistant on the likes of fiverr?
Assume you pay them and they remote in and do the wizardry needed. Not many on there from the UK though, seems to be a few from Vietnam listed as openwrt experts.
Your question is really not openwrt related.
That said, I would not use such services in general, but especially if you can over the individual who may “help” you as providing remote access to unknown/unvetted people can be extraordinarily dangerous.
Create threads here as necessary for resolving issues you are having with openwrt.
There's no doubt I'll be asking loads of questions… the more I read the more lost I'm getting. 
Thanks for replying @psherman
One basic generic advice, baby steps.
Start from defaults, get your WAN ~= internet access working and set up plain WLAN access (WPA2), once you've achieved that, you're golden.
From there on, tackle one problem, one additional feature individually -again, baby steps- with plenty of known-good config backups (bonus points for version control) inbetween. Keep your changes between known-good config states manageable and thereby avoid biting of more than you can chew.
Wise words and ones I will be trying my very best to follow..
Thanks everyone.
