Hi Nightshiftman!
I love the idea! Do your own thing! Definitely!!! If I had the skills, I'd do it! Shoot! If you were in San Diego, I'd help you!!! <smile> Forget maintenance! Except, maybe, as a marketing tool! You are craftsMAN!!! <smile>
A couple of thoughts:
1) You could come up with a few simple but cool designs to build and consign (with tank and sample livestock) to LFS or better yet... restraunts, doctor's offices, lounges... Any high traffic locations (retail or otherwise) that would benefit from having an enhanced decor! Maintain the tanks yourself only until you start making the big money!!! Then negotiate a contract with a local bonded maintenance company. Place a small, noticeable nameplate/price tag on each stand. The tank stays in a location after a prearranged timeframe only if it makes you money! This will provide incentive to the establishment's owner to push your product and you might be able to get them to sign a waiver for damages. It will take capital to start (buying stand materials, TOOLS!!! <smile>, the tanks and then stocking them...). I think it would fly though!!!
2) You could use the designs and/or tanks above or "borrow" pictures of ones that you can find on the internet and know you can reproduce and sell on ----!!! You can sell stand only or buy and sell the tanks by drop shipping them from the customer's general vicinity. Basically, you would need to establish wholesale contacts with tank manufacturers. Sell them on your going places new business. And, have the manufacturers drop ship and/or deliver to your customers -- their shipping liability. Tank manufacturers may even be able to provide you with leads/customers and maybe even sample/discounted pricing for the tanks in idea #1 above!!!
I don't think shipping is an insurmountable problem. Contact a few trucking companies and get quotes (using the various stand's weights and dimensions) to the furtherest locations you want to cover and add that freight into the price for a bottom line, delivered price. Or advertise plus shipping -- freight quotes upon request.
Sorry if I'm getting carried away! I would love to do something with my hands, make enough money to quit my day job and do it with the fishies!!! <smile>
