Do some 3D Modelling

Hi I'm Becky and I live in Coventry. I'm after someone to create digital 3D model of St. Bride's church steeple London. We have an historical link with the church as my fiance's 6th Great Grandfather used it as his inspiration to create the worlds first recognised tiered wedding cake. He was apprentice to a master baker who's daughter he fell in love with and wanted to show his father-in-law to be that he was worthy of his daughter. The loving husband and wife are burried in the grounds of the church and his wife's wedding dress and sprig of rosemary had been on show in the church until last year when it was removed for restoration. We had hoped to have the cake in the form of the steeple it'self but to do it justice with the detail involved it'd need to be huge and we can't afford that. So we thought that if we get a 3D model printed that would be better. Unfortunately for us there are no 3D models currently below £2800...so I thought if we could get a digital model made, if it's suitable we could use it, or use the digital model to 'print' a 3D model to put on the top of a more basic cake. We are after just the steeple & spire so working from the top down, the cone shape and the descending 4 sections. My Fiance has been researching his family tree for many years and has gone back 7 generations for all linked family members. He's really keen to include this as part of our wedding celebration along with a 'dit' (story) to tell our guests why our cake has a steeple on top of it. We are being married in May so would need this by the beginning of May 2017. Thanks for your attention. Hope to hear from someone. Becky & David
