As a way of ‘finding’ a Handyman online is fine. But any Handyman who quotes without seeing your job has to be a worry.
A lot of websites effectively get tradesmen to enter a bidding war assuming cheapest is best.
I once hired a labourer for $10 per hour. Bargain, I thought. Until he turned up and only had the use of one arm! True story.
My experience is that you usually get what you pay for.
