Although a storefront sign might look more professional, a vinyl sign is not a bad idea if it’s done correctly. I know many PT businesses that have a vinyl sign and they got a lot of attention and traffic thru their doors. Once you start making some money then you switch to a storefront sign (if needed). Also, some landlords might not allow vinyl signs, so check with your landlord. I hope this helps.
I have done both and quite frankly saw no difference in response or client traffic. The vinyl sign (large banner style) was actually easier to see most of the time. At night the illuminated sign was a bit easier to see, but I don’t think it made any difference in exposure overall. I haven’t invested money in an lighted sign since then. One spot did provide signage as part of the CAM for the building and to keep everyones’ signage consistent.
I’ve started out with a vinyl sign and upgraded to to an electrical sign. Start out with the vinyl sign. Make sure the print and color schemes are visible enough to see. Later on down the line upgrade to the electrical sign, but it’s ultimately up to you and your budget. Either one you choose it’s a win.
