Instead of creating a business with welcome gifts, I would suggest to create a 'new guest basket' which would be a new toilet brush, a new shower curtain, a new sponge and different toileteries which could be sold less than $10. As a host, I like to change my toilet bowl brush for every new guest. Last year, I could find one at 75 cents at Ikea (they removed it, and sell another around $1.5). The shower curtain, it takes me too long to walk to a Dollar Tree and so on... As another host already mentioned, if they provide a welcome gift, they usually prefer to make it themselves with local products or putting a cheap bottle of wine. Also, you must keep in mind that host do not want to spend too much money on it since it reduces their margins.
