Rental paperwork, payments, and deposits

[Taylor Witt]

My wife and I recently bought a family cabin, but we also want to rent it out by the week and/or month during times we aren't planning on being there.  Our County will not allow us to list on VRBO or Air BnB unless we list as a monthly rental, and they do monitor those websites.  Because of that I am going to create a flyer we can send to Realtors and post on Facebook and various sites.

Since we aren't using VRBO or Air BnB I will need to figure out a lease/paperwork for my renters to sign, a way for them to send payment and a deposit.

1. Where can I find rental documents specific to STR's?  What are those websites and what documents should I use?
2. What are the best ways to collect rent/security deposits - Vemno, PayPal, or others?
3. Better yet, is there a website (not Air BnB or VRBO) that could be used to handle all paperwork & deposit of payments?  That way I wouldn't need to piecemeal it together.

Is there anything else I'm missing or need to account for?
