You want asynchronous gigs with clear deliverables that fit into 60 to 120 minute blocks. The easiest place to start is small writing jobs like podcast show notes, blog post summaries, or product description rewrites. Put your $100 into a couple of clean portfolio samples and getting visibility on Upwork or Fiverr, using Canva to format samples and paying the small bidding or listing fees. Create three samples, set fixed prices like $35 for a 400 word summary, $50 for show notes with timestamps, and $30 per bundle of 5 product descriptions, then only pitch gigs that say no meetings. Batch your outreach on Sunday, save a proposal template, and aim for two quality pitches per week so it stays a habit rather than a second job.
Add quick win fillers like UserTesting, Prolific, or Respondent studies which pay roughly $10 to $50 per session and run 10 to 45 minutes, perfect for weeknights. If you like simple tech, offer micro tasks in Google Sheets such as Remove duplicates, TRIM to fix spaces, SPLIT or TEXTSPLIT to break fields, and VLOOKUP or XLOOKUP to merge lists, which often pay $20 to $35 an hour on fixed scope. For longer term upside, build and sell digital templates on Etsy or Gumroad like Notion dashboards, budgeting spreadsheets, or resume kits so your hour on Sunday creates an asset you can resell. Ship one template per week, write a clear use case and instructions, add screenshots, and reinvest early sales into better mockups and keywords. Protect your energy by time boxing to 90 minutes a night, setting a floor of $25 per hour effective pay, and declining anything with recurring meetings or same day turnarounds.
