Also, their direct booking website looks too amateur too.  

That's when there's less than $50-75 in actual supplies (drywall, tape, mud, paint) needed for the job.I had an amateur suggest that he could do it for a few hundred.

You are an amateur, you don't exist.

Hi everyone,I'm amateur and passive in real estate game and am looking for some guidance on how to best leverage my current assets to grow my portfolio. 

The feedback in the forums will likely be amateur hour on this. 

Better than an amateur evaluating a place and guessing what's wrong, not likely to miss something big after training, but really not qualified to tell you if X property is likely to make steady money as a rental after you fix what's obviously wrong or Y property is just going to be a total money pit.It's not like you and the roofing inspector/public adjustor space, where you go toe-to-toe against the insurance companies for real money.

What are the most successful strategies to go from amateur investor to a real professional ? 

I always say “If you think it’s expensive to hire a professional, wait until you hire an amateur.”

If there is any value I can provide in return even as an amateur, please let me know!
