Hey ladies...so after almost a year of being engaged the FI and I FINALLY set a date!!

We're looking at either the 14 or 15 of May...of this year

...yeah yeah short and crazy I know..but its a long story.
We are both from the Buffalo area originally and now live 2 hours south of San Antonio Texas. We were ready to just go to the courthouse down here and get married by ourselves but my future father in law is pretty sick and we both felt that he would be really hurt if he wasn't at his son's wedding. So..we want to basically do something small and easy in WNY. We are looking into the Water Street Landing in Lewiston for our reception. They've been great on the phone and our parents are going to have dinner there this weekend to check out the food and location. Has anyone ever been here? Thoughts?
Now we need to find a ceremony location. We dont really want a church wedding but if it was in a chuch/chapel that is non-denominational that would be okay. Also does anyone have suggestions on how to find a minister to perform the service? I would like something outdoors but the FI doesn't because he is afraid he is going to get sunburned if its super sunny out (he wears 100spf regularly lol). So something that was covered or indoors is fine. Just for the ceremony?
Just looking for ideas. Thanks!
