Just hire a handyman, painter, or friend to do it and provide a legitimate invoice.

I've seen/heard of too many cases where someone gets injured in a rental and then goes after the owner's personal assets.2) Part of making the LLC legitimate is to make sure both on paper and in practice- that it is separate from you.

Where would I get these types of forms or how do you guys create these forms so that it's legitimate?

There could be a legitimate reason, like they don't want to deal with it, or don't like the building any more... but you need to know this.

I had a situation before where the tenant was overly-anxious and called noise complaints on all of the other tenants (which were not legitimate) and I opted to end her lease.

It would be really dumb of you to not pull permits with a legitimate licensed contractor. #2 do you have a contract with him?

There is a Tenant's Union that will provide free legal aid to any tenant that wants it, whether it's a legitimate issue or they just want to screw the landlord. 

Are these legitimate wholesalers the very slim minority or is it more like nearly all other professions (doctor, mechanic, CEO) where the ones who stink give the rest a bad name?

Partner up with someone that has done some deals already so that you can legitimately say "We've purchased/rehabbed/developed X number of properties". 

Legitimate guys do some advertising there as well but man there are a LOT of losers that will be calling you non stop off your ad.I'd request photo's & references.
