I'm a member of a small community of Shopify consultants and app developers.
This year, like every year around this time, conversations start up around about when people stop accepting new clients for the rest of the year. Some already have and are planning projects for 2020 right now.
Just like you and your store has a cycle of busy and lean times, Shopify consultants do too.
Typically they start getting busy and turning away work in October and accept their last clients in November. That lead-time is needed so that everything can be finished before Black Friday and beyond.
(Though some stores keep consultants on retainer and working on projects year-round)
If you've been wanted to get help with your Shopify store before the end of the year, you're going to want to start talking with people this week. Otherwise you run the risk of missing out on their schedule.
If you know you need help but you aren't sure who to talk to, I keep a list of Shopify people I recommend. It's a short list as I've worked with or talked with everyone on it frequently, some every day.
