If I could reduce my symptoms, I could easily earn the money I need to survive.
Sharpening knives. It worked before.
I paid 80 pesos (plus shipping) for 2.5L, but I could have bought 100L for 500 pesos.
Gross revenue: 100 / 2.5 = 40 packages for $80 each is 40*80=3200 pesos.
Selling prepared agar plates.
They sell for $150 per plate, plus shipping.
I would need to purchase sterile, plastic, Petri dishes. MXN$2800 for 1152 plates.
I have 440g of excess, dry agar. 39g of dry agar makes 1000ml of liquid agar.
Each plate holds 10ml of liquid agar.
440g÷39g×1000ml÷10ml = 1128 plates.
Gross revenue: 1128*150=MXN$169,200
Gross profit: 169,200-2800=MXN$166,400
Other potential costs:
3-5% transaction fee for credit cards
Labor for one or more of the following: cold-calling diagnostic clinics (those clinics are everywhere in Mexico), making the plates, fulfilling internet orders.
Shipping materials (or put it in the cost of shipping)
“Breakage.” Preparing agar require skill and precision
If my symptoms were manageable, I could easily earn money with the three methods, above. Of course, there are many other things I could do such as teach English, sell spores, or start one of my many business ideas.
