Month 2: Add Website Chatbot ($29). Tidio or similar captures leads and handles FAQs 24/7. Setup takes 2-3 hours one-time. Typical small business gets 5-10 extra qualified leads monthly from after-hours chatbot conversations. At 20% close rate and $1,000 average customer value, that's $1,000-2,000 monthly revenue from $29 tool = 3,448-6,897% ROI.

Scale with Proven Results

Month 3-6: Add Marketing Tools ($50-100). Once ChatGPT and chatbot prove value, add Canva Pro for graphics, Jasper for dedicated copywriting, or email automation tools. Each addition targets specific pain point and delivers measurable improvement. This gradual rollout builds expertise and demonstrates value before expanding budget.

Month 6+: Consider Custom Solutions.
