Use Adobe Illustrator's Image Trace feature to create an SVG logo.

So do you want:
[A] a font that mimics the above graphic, or
[B] are you looking to establish a brand font that works with the signature above?

If [B] then I would try to find something that compliments rather than matches. It would depend also on the type of work the person does. Some ideas: A typewriter font to reinforce a handmade charm, a modern sans serif to be fairly neutral and let the signature be the star, a classy didone for an upscale gallery feel, something that reflects the loops and ascenders of the signature in a simple sans.

Hope that helps!
