Photoshop Merging HDR pictures (Urgent)

I have a lot of separate HDR pictures that need to be merged to create single picture with the best features. Can be done on Photoshop or Lightroom or any other app you prefer. Don't have a lot of budget at the moment but there's a lot of work if this goes well. Needs to be done within 24 hours. Need someone who can start working as soon as the project is accepted. URGENT! Don't need jack of all trades master of none. Please apply only if you know photo editing in depth.
