Need architect for children's play place

We are looking for the services of an architect to help us design an attractive 6,300-ish square foot children's play place (70 x 90?). It is in a commercial subdivision right across from a brand new Hampton Inn. While it will be mostly open and empty inside to allow space for the play equipment, we do want to include an overlooking balcony over the front 3rd of the building (over the restrooms, front door, and party rooms). We would like fancy/stylish stairs leading up on either side. We want to include a large window facing north towards the Hampton Inn to showcase the fun equipment inside and entice hotel occupants to come in. We would like recommendations on window placement, situation of the building on the lot, and parking. I feel like we mostly know what we want but I want formal designs for my builder to use and recommendations to make it as aesthetically pleasing as possible (within a reasonable budget). The lot size is 0.42 acres, but considering a larger lot if absolutely necessary. See attachments. Thanks!
