I'm thinking of creating an application online and making a website. 

Check out other online guides available here: https://www.biggerpockets.com/guides3.

I know you mentioned wanting to buy locally and that is always the first choice - when we have a choice.

Lease Management - Avail.co, Apartments.com, Buildium, TenantCloud,  - many others - they can List For Rent, Schedule Showings, Provide Applications, Screen Tenants, Setup Leases, Setup and Manage Rent Payment, and other things (keep track of maintenance, keep track of expenses and make reports for accountants etc) Tenants like it because its online and makes it clear what they need to do - This also helps answer Drews question to you. - Showing a property - I have less to say on this one, looking for ideas myself.

If I like them and they meet the criteria I ask them to apply online.

@Rhett Tullis  is there much new apartment construction coming on line in OKC for 2024? 

Every person's choice is own or rent.

I thought I had already taken care of the paperwork they are requesting but I have another letter from them.In the mean time I did go online for Wells Fargo and their business accounts allows you to mark up to 3 states and being registered in WY was not an issue. 

It seems like that would be a question to ask the attorney that set up the trust up.Can you not get courtroom legal defense from the attorney that set this up - or is this person just telling you comply with the subpoena you have no choice ? 

Some clients might not mind meeting you at properties, or you could offer them the choice to either drive themselves or join you in a rideshare, like you mentioned.
