Unhinged Rant About my New Handyman Business

I've been running my handyman business for 5 months, more than 200 one-off jobs completed and 4 subcontracts done, with some commissions made on the side. I'm making enough to call this a part-time/casual job, but I'm trying to do this full time by getting on vendor lists.

I have a business profile with tons of pictures and about 25 Google reviews, averaging 4.7 stars, and a professional website. Don't have a van yet, just a car stuffed with work equipment. I have been managing my debt well, paying off what I can, but still $1200 unpaid.

My main issue is not the work; it's the primitive & 3rd world cheap clients. It's not that they can't afford my service, these people can certainly afford it, and I know this because they have multiple homes, businesses, and vehicles, but they turn down my reasonable quote just because they love the cheapness. They ask for a discount and want me to make material purchases on my maxed out credit card, and sometimes cancel after I make a non-refundable purchase. However, they don't have a problem paying a higher quote or leaving a tip for a worker with a similar ethnic background. They think so primitively, that they expect me to accept an employee's hourly wage for a small job, because they don't understand anything beyond hourly wage, and the costs that I have to account for after the business expenses such as insurance, licences, fuel, maintenance, tools, etc.

For example, $62.34 quote to replace a ceiling track light same day was rejected, $87.21 quote to replace a ceiling fan same day was rejected, worked 3 days at the agreed rate of 25 an hour digging the ground to get a pipe modified to allow drainage and received only 1 day worth of pay and lunch, partial payment and job cancellation because the painters on the job site incorrectly installed all the door hinges, thereby extending the job from 1 day to 2 days, and they didn't want to wait 2 days, so they deceived me and my carpenter by paying partially for 1 day and then refusing to pay the cancellation fee we agreed on, followed by a 1 star review.

On the other hand, I've had great clients from the urban areas (and occasionally a few from suburban areas) who left me large tips, had no problem with my quotes, and recommended me to subcontractors who I got to work with on larger projects. I miss these type of clients, and want to avoid the primitive & cheap NPCs mainly occupying sub urban areas.

TLDR; need to know how to get real clients instead of cheapskates.
