Not a simple job (imo).

Yes the size of the upper cuspid is an issue trying to make it
look more like a lateral incisor.

Root canals may or may not be an issue.

The upper left lateral will end up quite thick to make it look
'straight' with the other teeth.

Cross bite on the right side?  Clenching?

IMO, orthodontic treatment would be the first choice with perhaps
an implant for the upper right lateral afterwards (temp tooth on
a retainer would buy you time financially before the implant).

Sometimes you get what you pay for and sometimes you get less.
